This change introduces a refactoring of the gRPC protocol subsystem that allows the creation of a gRPC chanel independently of the client, while allowing multiple clients to share the same channel (e.g. as in Stratum where we use 3 clients). Moreover, we refactor the P4RuntimeClient API to support multiple P4Runtime-internal device ID using the same client. While before the client was associated to one of such ID. Finally, we provide an abstract implementation for gRPC-based driver behaviors, reducing code duplication in P4Runtime, gNMI and gNOI drivers. Change-Id: I1a46352bbbef1e0d24042f169ae8ba580202944f
