Fall back to non-containerized cinder-volume to unblock CI

Fall back to non-containerized cinder-volume to unblock CI

CI was stuck on collecting logs. The collect-logs playbook, which
normally takes just a few minutes, took more than an hour and was
eventually killed.

The playbook was stuck on collecting LVM info on the overcloud node,
which runs this command:

  (vgs; pvs; lvs) &> /var/log/extra/lvm.txt

Therefore it's very likely that the problematic part is the LVM setup
in the containerized cinder-volume service, and falling back to
non-contianerized for the time being should get the CI going
again.
