Niels de Vos c9e64f9478 deploy: make the csi-*plugin containers the default for kubectl commands
When issues or bugs are reported, users often share the logs of the
default container in a Pod. These logs do not contain the required
information, as that mostly only can be found in the logs of the
Ceph-CSI container (named csi-cephfsplugin or csi-rbdplugin).

By moving the Ceph-CSI containers in the Pods to the 1st in the list,
they become the default container for commands like `kubectl logs`.
