If there is only one galera node, it should bootstrap automatically

[Jesse Pretorius]

In small environments, usually for testing or for very small production environments, there may only be one galera node in the environment. The environment may grow over time to have more nodes.

Ideally if there is only one host in the 'galera_all' group, the cluster should automatically be bootstrapped if the galera host/container is rebooted.

    On single nodes use an empty cluster address

    When there is only one galera node, configure galera with an empty
    cluster address. Each time the mysql service starts on this node it will
    automatically create a new cluster.

    Allow a single-node MariaDB cluster to restart properly

    With the implementation of https://review.openstack.org/382683 a single
    MariaDB node has no peers configured, so there's no need to bootstrap
    the cluster on restart.

    This patch removes the condition in the handler which previously was
    needed to handle the re-bootstrap during a single node cluster service
    restart.
