      .Instances with ephemeral storage on NFS share continue working after Compute service restart

      Before this update, Compute service (nova) instances with ephemeral storage on NFS shares stopped working as soon as the containerized Compute agent service restarted on the hypervisor host.

      With this update, Nova Compute service instances with ephemeral storage on NFS shares no longer stop working. The Nova Compute init container is triggered every time an Openstack Dataplane Deployment is created with the Nova EDPM service that is included into the linked Openstack Dataplane Nodeset, and corrects the permissions of the `/var/lib/nova/` directory contents on hypervisors.

      in RHOSO, we have returned a recursive change of nova's ownership to /var/lib/nova. That brings back a 6 y.o. tripleo issue with NFS backend https://bugs.launchpad.net/tripleo/+bug/1778465
