/**
* Helper to log gRPC request and response message to the data buffer for a service.

* It should be called using a "with" statement each time an RPC is received such that
* the request and response proto messages can be passed in. It will automatically log
* the request and response to the data buffer, and mutates the headers to add additional
* information before logging.
* @param {protobuf} response Any gRPC response message with a bosdyn.api.ResponseHeader proto.
* @param {protobuf} request Any gRPC request message with a bosdyn.api.RequestHeader proto.
* @param {DataBufferClient} [rpc_logger=null] Optional data buffer client to log the messages; if not
  provided, only the headers will be mutated and nothing will be logged.
* @returns {void}
