Fix marvell-armhf build break

The azure-storage package depends on the cryptography package. Newer
versions of cryptography require the rust compiler, the correct version
for which is not readily available in buster. Hence we pre-install an
older version here to satisfy the azure-storage dependency.
Note: This is not a problem for other architectures as pre-built versions
of cryptography are available for those. This sequence can be removed
after upgrading to debian bullseye.

sonic-net/sonic-utilities#1431 changes the path to the udevprefix.conf file. The file previously inappropriately resided in the <platform>/plugins/ directory. That directory is reserved for now-deprecated Python platform plugins, and will be removed in the near future.

Commits include:

* src/sonic-utilities c7e46c9...42cab68 (3):
  > [consutil] Look for udevprefix.conf file under platform dir, not plugins (sonic-net#1431)
  > [ci]: download from sonic-buildimage.vs artifact (sonic-net#1428)
  > [storyteller] sort output by time and improve lag support (sonic-net#1430)

* Add *MUX_CABLE_TABLE* to set of tables to clear on SWSS start, which
will clear HW_MUX_CABLE_TABLE and MUX_CABLE_TABLE
* Order swss to start before pmon to ensure that DBs are cleared before
xcvrd (running inside pmon) starts and re-populates the tables

- What I did
All SWSS dependent services should stop before SWSS service to avoid future possible issues.
For example 'teamd' service will stop before to allow the driver unload netdev gracefully.
This is to stop all LAG's before restarting syncd service when running 'config reload' command.

- How I did it
Change the order of dependent services of SWSS.

- How to verify it
Run 'config reload' command.
Previously the operation failed when a large number of PortChannel configured on the system.

Update topology script to retrieve hwsku from minigraph
if hwsku information is not available in config_db.
Fix clean up of interfaces in msft_multi_asic_vs hwsku
topology script.
- Why I did it
When bringing up multi-asic VS switch, topology service is started during boot up.
Topology service starts a shell script which runs the topology script present in /usr/share/sonic/device// directory. To invoke hwsku specific script, the topology script tries to retrieve hwsku information from config_db.
During initial boot up config_db might not be populated. In order to start topology service before config_db is updated,
update topology script to get hwsku information from minigraph.xml if it is available.
This will be helpful to bring up multi-asic VS testbed by loading minigraph and starting topology service.
- How I did it
Update topology.sh script to retrieve hwsku information from minigraph.xml.
Fix clean up function on msft_multi_asic_vs toplogy script.
- How to verify it
single-asic VS - no change; topology service is only enabled for multi-asic VS.
multi-asic VS - Bring up multi-asic VS image, copy minigraph to vs image, start topology service. Topology service should be successful.
to test clean up function fix, start topology service - make sure interfaces are created and moved to the right namespaces.
stop topology service - make sure namespace do not have any interface and all front end interfaces are present in default namespace.

- Why I did it
Current mutli-asic vs hwsku consists of 6 asics with each asic having 32 interfaces. When bringing this up, below issue was seen:
When all 32 interfaces(sonic interfaces and linux interface) are set to 9100 mtu, DMA error is seen "DMA: Out of SW-IOMMU space for 4096 bytes at device 0000:06:03.0" which can be fixed by updating swiotlb=65536 in /host/grub/grub.cfg .In order to keep multi-asic VS lighter and easier to bring up and test, new hwsku 'msft_four_asic_vs' is added to represent 4-asic hwsku with 2 frontend asics and 2 backend asics and each asic having 8 interfaces interconnected by port-channels.
- How I did it
Add msft_four_asic_hwsku directory to have the right number of directories (4) and update port_config.ini and lanemap.ini files to include 8 ports information.
Add topology.sh script to create the internal asic-asic connectivity.
- How to verify it
Update asic.conf with the 4 asic information as below and build sonic-vs.img:
NUM_ASIC=4
DEV_ID_ASIC_0=0
DEV_ID_ASIC_1=1
DEV_ID_ASIC_2=2
DEV_ID_ASIC_3=3
Modify sonic_multiasic.xml to have 8 front panel interfaces.
create virtual switch using "sudo virsh sonic_mutliasic.xml" command.
Start topology service and Load config_db files for switch and each asic.
Ensure that that all internal interfaces and port_channels are coming up.
multi-asic vs testbed:
Bring up mutli-asic VS testbed with a multi-asic image(asic.conf updated to 4 asics) and using t1-lag topology.
./testbed-cli.sh -t vtestbed.csv -m veos_vtb -k ceos add-topo vms-kvm-four-asic-t1-lag password.txt

Support new SKU under the name of SN2700-D40C8S8

- Why I did it
Fix DPB crash caused of new entries in config db.
Details: sonic-net#6331

- How I did it
Updated crm yang model

The S6000 devices, the cold reboot is abrupt and it is likely to cause issues which will cause the device to land into EFI shell. Hence the platform reboot will happen after graceful unmount of all the filesystems as in S6100.

Moved the platform_reboot to platform_reboot_override and hooked it to the systemd shutdown services as in S6100

 - Fix parent `__init__` call for platform API, based on sonic-net/sonic-platform-common#173
 - Implementation for more platform API methods
 - Daily storage information reporting in `arista daemon`
 - Enhancements to reboot cause reporting, now multi-sourcing reboot cause information
 - Miscellaneous fixes

#### Why I did it

To incorporate the below changes in DellEMC S5232, Z9264, Z9332 platforms.

- Update thermal high threshold values
- Make watchdog API Python2 and Python3 compatible
- Fix LGTM alerts
- Z9264: Fix get_change_event timer value

#### How I did it

- Use 'universal_newlines=True' in subprocess.Popen call.
- Change the timeout in 'get_change_event' to milliseconds to match specification in sonic_platform_common/chassis_base.py

- Why I did it
System is stuck on 'starting' state on SimX platform because of infinite loop on 'hw-management-ready.sh' script .
The loop is polling to check if the hw-mgmt sysfs created before proceeding with the flow, for SimX platform the sysfs will never create so the system is not starting properly.

- How I did it
Add a condition to poll on hw-mgmt sysfs only if the switch is real HW and not SimX platform.

- How to verify it
Check "systemctl status hw-management.service" output on a SimX switch with this patch, the state will be "active".

What I did:-

For multi-asic platforms added iptable v4 rule to communicate on docker bridge ip
For multi-asic platforms extend iptable v4 rule for iptable v6 also
For multi-asic program made all internal rules applicable for all protocols (not filter based on tcp/udp). This is done to be consistent same as local host rule
For multi-asic platforms made nat rule (to forward traffic from namespace to host) generic for all protocols and also use Source IP if present for matching

#### Why I did it

In preparation for the merging of sonic-net/sonic-platform-common#173, which properly defines class and instance members in the Platform API base classes.

It is proper object-oriented methodology to call the base class initializer, even if it is only the default initializer. This also future-proofs the potential addition of custom initializers in the base classes down the road.

Why I did it
In the configuration of rsyslog, duplicate messages will be suppressed and reported in the format of message repeated n times.
Due to this behavior, if a critical process in a container exited unexpectedly, the alerting message will be written into syslog once
and not be written into syslog anymore until the second critical process exited. This PR aims to differentiate these alerting messages such that they will not be suppressed by rsyslogd and can appear in the syslog periodically.

How I did it
This PR adds a counter into the alerting message and shows how many minutes a critical process was not running.

How to verify it
I verified and test this implementation on a physical DUT.

Enable BBR config allowas-in 1 for internal peers

Why I did:
To advertise BBR routes learnt via e-BGP peer in one asic/namespace to another iBGP asic/namespace via Route Reflector.

…pport a… (sonic-net#6831)

To fix [DPB| wrong aliases for interfaces](sonic-net#6024) issue, implimented flexible alias support [design doc](sonic-net/SONiC#749)

> [[dpb|config] Fix the validation logic of breakout mode](sonic-net/sonic-utilities#1440) depends on this

#### How I did it

1. Removed `"alias_at_lanes"` from port-configuration file(i.e. platfrom.json) 
2. Added dictionary to "breakout_modes" values. This defines the breakout modes available on the platform for this parent port, and it maps to the alias list. The alias list presents the alias names for individual ports in order under this breakout mode.
```

    "interfaces": {
        "Ethernet0": {
            "index": "1,1,1,1",
            "lanes": "0,1,2,3",
            "breakout_modes": {
                "1x100G[40G]": ["Eth1"],

                "4x25G[10G]": ["Eth1/1", "Eth1/2", "Eth1/3", "Eth1/4"],
                "2x25G(2)+1x50G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"],
                "1x50G(2)+2x25G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"]
            }
        }

#### Why I did it
Some platforms have difficult to attach egress ACL to vlan.

#### How I did it
For egress ACL attaching to vlan, break them into vlan members.

#### How to verify it
Unit test
Tested in DUT

1. Made the command next-hop-self force only applicable on back-end asic bgp. This is done so that BGPL iBGP session running on backend can send e-BGP learn nexthop. Back end asic FRR is able to recursively resolve the eBGP nexthop in its routing table since it knows about all the connected routes advertise from front end asic.

2. Made all front-end asic bgp use global loopback ip (Loopback0) as router id and back end asic bgp use Loopbacl4096 as ruter-id and originator id for Route-Reflector. This is done so that routes learnt by external peer do not see Loopback4096 as router id in show ip bgp <route-prerfix> output.

3. To handle above change need to pass Loopback4096 from BGP manager for jinja2 template generation. This was missing and this change/fix is needed for this also https://github.com/Azure/sonic-buildimage/blob/master/dockers/docker-fpm-frr/frr/bgpd/templates/dynamic/instance.conf.j2#L27

4. Enhancement to add mult_asic specific bgpd template generation unit test cases.
