[201911] show interface portchannel support for Multi ASIC

[arlakshm]

Signed-off-by: Arvindsrinivasan Lakshmi Narasimhan arlakshm@microsoft.com

- What I did
Add support for multi ASIC CLI options for show interface portchannels
2 new options have added

• [-n, --namespace] to allow user to display the information for given namespaces
  If this option is not present the information from all the namespaces will be displayed

• [-d, --display] to allow user to display information related both internal and external interfaces
  If this option is not present only external interfaces/neighbors will be display

One single ASIC platform, this options are not valid, so the behavior remains unchanged

- How I did it

• Change the teamshow script to get the port channel information from all the Namespaces
• Add support for -n and -d options
  This new options are ignored for single ASIC platforms

- How to verify it
Help menu on multi ASIC platforms

admin@sonic:~$ show interface portchannel -h
Usage: show interface portchannel [OPTIONS]

  Show PortChannel information

Options:
  -d, --display [all|frontend]    Show internal interfacees  [default:
                                  frontend]
  -n, --namespace [asic0|asic1|asic2|asic3|asic4|asic5]
                                  Namespace name or all
  --verbose                       Enable verbose output
  -?, -h, --help                  Show this message and exit.
