Fix for miscellaneous watchdog issues. (Muhammad Usama)
The lost nodes reported by life-check are treated as hard failures even when the node is reachable from the watchdog core.
In the case of network partitioning or partial life-check failure, the kicked out standby node was too aggressive in trying to connect to the master or become a master itself so that potentially put the unnecessary burden on the network and the cluster nodes. Fix is to make the isolated node a bit calm and wait between trying to connect to master or become a master.
