    Allow setting gmcast.peer_timeout value

    In some resource constrained environments particularly during deploy
    time percona-cluster nodes can experience time outs during inter-node
    communication.

    This changes makes the gmcast.peer_timeout configurable based on the
    galara cluster documentation:
    http://galeracluster.com/documentation-webpages/galeraparameters.html

    Warning: Changing this value from the default may have unintended
    consequences. This should only be used when constraint's call for it.
