Implement the APIs for gRPC calls in client/server

Implement the APIs defined in the RdcStandaloneHandler to make gRPC call to daemon

Implement the APIs defined in the RdcAPIServiceImpl to handle the gRPC calls in daemon

Add two APIs to get all GPU groups and field groups: rdc_group_get_all_ids()
and rdc_group_field_all_ids()
Those two APIs are required by the rdci group and fieldgroup
sub-modules.
