Added support to add gbsyncd in Feature Table of Host Config DB (soni…

…c-net#11754)

Why I did:

In case of multi-asic platforms gbsyncd is not getting added to Feature Table of Host Config DB. Without this container_checker complains of not needed gbsyncd container's are running.

How I did:
Update Both Host and Namespace config db when gbsyncd docker is starting.

How I verify:
Verified on Multi-asic platforms.
