[COMMON] add pre upgrade script for mariadb-galera
When upgrading from a version to another, it may be impossible to do it "simply" because of changes in immutable properties of statefulsets. We change that here by creating a temporary deployment which will hold the whole databases during the time the old statefulset gets destroyed and the new one gets created.
