Deletion of Resources on Custom Resource deletion

currently if a mysqlinstancecontroller resource is deleted the underlying resources like the deployment , service , configmap etc are still present.

These must be removed on deletion of the resource.

Start by tracing the MySQLInstanceController reconciliation and deletion handling for a mysqlinstancecontroller resource. Check how the underlying Deployment, Service, ConfigMap, and other resources are created, then verify that deleting the custom resource removes them all and that the controller's tests cover this behavior.
