Fix for bug-545: Quorum lost and not recovered

Master watchdog node was not adding the lost standby node to its list of valid
standby nodes after it is rediscovered by the lifecheck.The fix is to ask the
node to rejoin the master node when it gets rediscovered by the lifecheck.
As part of this commit, I have also added the watchdog data version and Pgpool-II
version in the watchdog info packet to make the extensions in the watchdog
messages easier in the future.

Thanks to Guille(reporter of this bug), for providing lots of help in testing the fix
