This PR adds logic to add the following gRPC relevant telemetry schema fields in the state DB table
MUX_CABLE_INFO

1) "self_link_state"
2) "up"
3) "peer_link_state"
4) "up"
5) "self_oper_state"
6) "up"
7) "peer_oper_state"
8) "up"
9) "server_version"
10) "1.0"
11) "grpc_connection_status"
12) "READY"
13) "self_mux_direction"

This data will allow telemetry to check gRPC stats and version of the server and be able to raise alert if needed appropriatley.

Description
gPRC data for telemetry
appropriate logic is added for handling the gRPC stats and RPC's are called and counted as appropriate

Motivation and Context
How Has This Been Tested?
UT and putting the changes on the testbed
