Added Support for deployment_id parsing for Device Asic metadata (#11454)

What I did:
Added Support for deployment_id parsing for Device Asic metadata.

Why I did:-
Deployment Id is used in BGP docker for FRR template generation. For multi-asic platforms running in namespace without deployment id as key in DEVICE_METADATA FRR template generation fails. This change is needed after this #10154 where if deployment_id is none we don't update DEVICE_METADA dictionary.

How I verify:-
Added unit-test.
