ctdb-daemon: Implement ctdb_control_startup()

Browse Source 
This doesn't implement what was recommended.  That would require
careful error handling, probably with a fallback to this code anyway.
This is simple and does no worse that the current code.  That is, the
new node is updated on the next call to tdb_update_tcp_tickles().
