    Replace wait-for-haproxy-backends with puppet type

    * Implement a special puppet type to wait until haproxy backend is online.
    * Wait for mysqld backend as a requirement for nova and keystone backends
    * Switch to TCP connect for cluster check instead of UNIX socket:
      - the host to connect is the node's management IP
      - the port is the mysql HAProxy backend port, 3307
      - the user is clustercheck and its password is the same as wsrep user has
      - the timeout is 10 seconds
    * Parametrise galera cluster check class and script
    * Move galera::cluster check to opesntack module (otherwise, there are
      4 more classes to drag all the cluster check parameters through,
      including puppet-mysql module which does not have these params in upstream)
    * Fix docs for cluster check class parameters
