- External PHY is managed via gearbox (gbsybcd docker container) in SONiC
- Enhanced 'External PHY management' from SONiC's single-ASIC environment to multi-ASIC
- Enhanced gbsyncd docker container from single Namespace to multi-Namspace mode
- Added gbsyncd.service.j2 on per_namespace basis.
- Each namepace/ASIC now to have its unique gbsyncd<ASIC#> docker container with its
own Gearbox table, redis-DB
