Fairly large changeset to enable better control

* Nodes in a galera cluster now managed via chef roles
  with a Chef search returning a set of nodes having
  a specified chef role and a matching cluster name
* Hopefully handles the OOO issues with the initialization
  of the reference cluster node and then restart
  of the mysql service
