Radosław Piliszek 9f14ad651a Fix multiple issues with MariaDB handling ... These affected both deploy (and reconfigure) and upgrade resulting in WSREP issues, failed deploys or need to recover the cluster. This patch makes sure k-a does not abruptly terminate nodes to break cluster. This is achieved by cleaner separation between stages (bootstrap, restart current, deploy new) and 3 phases for restarts (to keep the quorum). Upgrade actions, which operate on a healthy cluster, went to its section. Service restart was refactored. We no longer rely on the master/slave distinction as all nodes are masters in Galera.
