Revert "[Discovery] immediately start Master|Node fault detection pinging" 

In #6706 we change the master validation to start pining immediately after a new master as ellected or a node joined. The idea is to have a quicker response to failures. This does however create a problem if the new master has yet fully processed it's ellection and responds to the ping with a NoLongerMasterException. This causes the source node to remove the current master and ellect another, only to find out it's not a master either and so forth. We are moving this change to the feature/improve_zen branch, where the improvements we made will cause the situation to be handled properly.

This reverts commit ae16956e07.
