Type of Change

Description

I have implemented a gRPC client that facilitates communication with the recovery-decider gRPC service. The client should be capable of initializing and managing the connection to the service, sending requests, and handling responses in accordance with the defined service contract (protobuf definitions).

Additional Changes

This PR modifies the API contract
This PR modifies the database schema
This PR modifies application configuration/environment variables

Motivation and Context

How did you test it?

@Aprabhat19 @srujanchikke Ideally you folks should consider using an equivalent of Secret on the gRPC server side as well, similar to how the connector-service folks are doing...

Nit: Can't we accept a reference here? Do you necessarily need an owned value?

Same here, can't we accept a reference?
