Change subject: stasis: Remove stringfields and lock from change message.
......................................................................

stasis: Remove stringfields and lock from change message.

When a subscribe or unsubscribe occurs a message is published
containing this information. This change makes it so that the
message no longer uses stringfields or a lock, as both are not
really needed for the message.
