Base class for sessions being hosted in other cluster nodes. Almost all
messages will be forwarded to the actual session in some remote cluster node.
Only some few messages will be local operations like getting the session's address
or the session status. And only some operations will be cached locally for a brief
period for content that is highly used and not frequently modified.
