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 Change-Id: If8e0b3f9e4f317fde5328e71115aab87a5fa655f
