[VOL-4514]  Addressing device reconciliation failure

This commit consists of augmention the current GetHeathStatus()
API on the grpc server with the grpc client information.  This
provides the grpc server with more insights of the grpc client
connection status.  This is useful for a server to know whether it
is more likely to receive a response following a request from a
remote server, represented by the grpc client(s).  For now this is
used by the openonu adapter to figure out when it can send an
OMCI request to the openolt adapter following a restart of the
onu adapter.
