    MariaDB: create clustercheck user at container bootstrap

    In HA overclouds, the helper script clustercheck is called by HAProxy to poll
    the state of the galera cluster. Make sure that a dedicated clustercheck user
    is created at deployment, like it is currently done in Ocata.

    The creation of the clustercheck user happens on all controller nodes, right
    after the database creation. This way, it does not need to wait for the galera
    cluster to be up and running.

    Partial-Bug: #1707683
