Add creates a new MysqlCluster Controller and adds it to the Manager with default RBAC. The Manager will set fields on the Controller
and Start it when the Manager is Started.
USER ACTION REQUIRED: update cmd/manager/main.go to call this mysql.Add(mgr) to install this Controller
Reconcile reads that state of the cluster for a MysqlCluster object and makes changes based on the state read
and what is in the MysqlCluster.Spec
