Service-specific metadata associated with the operation. It typically
contains progress information and common metadata such as create time.
Some services might not provide such metadata. Any method that returns a
long-running operation should document the metadata type, if any.
The server-assigned name, which is only unique within the same service that
originally returns it. If you use the default HTTP mapping, the
name should be a resource name ending with operations/{unique_id}.
The normal response of the operation in case of success. If the original
method returns no data on success, such as Delete, the response is
google.protobuf.Empty. If the original method is standard
Get/Create/Update, the response should be the resource. For other
methods, the response should have the type XxxResponse, where Xxx
is the original method name. For example, if the original method name
is TakeSnapshot(), the inferred response type is
TakeSnapshotResponse.
