Subject: [PATCH] Make reset work for crio (#6812)

crio refuses to delete pods when cni is unavailable which is the
case e.g. using calico with kdd datastore. See:

https://github.com/cri-o/cri-o/issues/4084

Fix by deleting storage associated with containers. Stop and disable
crio service so switching container runtime can be done.
