- Includes the following commits:
    - [bcmshell.py] Match extra whitespace before prompt in regex (#3)
    - add support for qsfp28 eeprom (#2)

- What I did

Fixed vanilla teamd bug, which prevented teamd to have a correct view of kernel state. Check bug #2 from the message
Changed schema for LACP port id.
Changed severity of an error message.
Removed logic to disable warm_start_read mode, when teamd started. It didn't work in system restart mode, because interfaces were added one by one, and it's impossible to say when everything is added.

- How I did it

I've added team_refresh() on every port addition
I extract port id from the port name. Currently I support only "EthernetX" scheme. We need to add more schemes if we change port scheme.
_err -> _info
...

- How to verify it
Build the image, install on your DUT, reboot it once, then reboot it on WR mode checking LACP state on remote side. The state shouldn't flip.

Currently, ASAN sometimes reports the BufferOrch::m_buffer_type_maps and QosOrch::m_qos_maps as leaked. However, their lifetime is the lifetime of a process so they are not really 'leaked'.
This also adds a simple way to add more suppressions later if required.

Example of ASAN report:

Direct leak of 48 byte(s) in 1 object(s) allocated from:
    #0 0x7f96aa952d30 in operator new(unsigned long) (/usr/lib/x86_64-linux-gnu/libasan.so.5+0xead30)
    #1 0x55ca1da9f789 in __static_initialization_and_destruction_0 /__w/2/s/orchagent/bufferorch.cpp:39
    #2 0x55ca1daa02af in _GLOBAL__sub_I_bufferorch.cpp /__w/2/s/orchagent/bufferorch.cpp:1321
    #3 0x55ca1e2a9cd4  (/usr/bin/orchagent+0xe89cd4)

Direct leak of 48 byte(s) in 1 object(s) allocated from:
    #0 0x7f96aa952d30 in operator new(unsigned long) (/usr/lib/x86_64-linux-gnu/libasan.so.5+0xead30)
    #1 0x55ca1da6d2da in __static_initialization_and_destruction_0 /__w/2/s/orchagent/qosorch.cpp:80
    #2 0x55ca1da6ecf2 in _GLOBAL__sub_I_qosorch.cpp /__w/2/s/orchagent/qosorch.cpp:2000
    #3 0x55ca1e2a9cd4  (/usr/bin/orchagent+0xe89cd4)

- What I did
Added an lsan suppression config with static variable leak suppression

- Why I did it
To suppress ASAN false positives

- How I verified it
Run a test that produces the static variable leaks report and checked that report has these leaks suppressed.

Additionally, changed the series file and renamed the 0002 patch as 0001 patch as this is the only patch on this branch right now.

…h expression (sonic-net#19)

Why I did it
Adding YValidator support so that xpath expression (must/when/leafref) can be evaluated using custom xpath engine. Custom xpath engine will be integrated in subsequent PR.

How I did it
N/A.
Please refer to change log for more details.

How to verify it
No specific test cases to be executed. Run cvl go test cases using - 'make cvl-test'.

Description for the changelog

Modifying cvl.go for adding new data structure to store cache in CVL session cache, add YValidator data type. Adding API to get Redis table name from YANG list.

Modifying cvl_api.go and cvl_cache.go due to change in session cache.

Modifying cvl_syntax.go due to change in API name.

Modifying cvl_semantics.go to add various API which can operate on YValidator nodes.
