Memcached instance resource name in the format:
``projects/{project_id}/locations/{location_id}/instances/{instance_id}``

This corresponds to the ``name`` field
on the ``request`` instance; if ``request`` is provided, this

should be retried.
timeout (float): The timeout for this request.

An object representing a long-running operation.

you can re-use to avoid defining duplicated empty
messages in your APIs. A typical example is to use it as
the request or the response type of an API method. For
instance:
