Update management interface related configuration in MGMT_PORT_TABLE STATE_DB

[SuvarnaMeenakshi]

…in STATE_DB

Why I did it

Currently Management interface related data is present in CONFIG_DB and 'oper_status' is present in STATE_DB MGMT_PORT_TABLE.
This PR change is made to ensure that all telemetry data related to management interface is present in STATE_DB.
