[SPARK-12614][Core]Don't throw non fatal exception from send or ask
Right now RpcEndpointRef.send/ask may throw exception in some corner cases,
such as calling send/ask after stopping RpcEnv. It's better to avoid throwing
exception from RpcEndpointRef.send/ask. We can log a warning for `send`, and
send the exception to the future for `ask`.
