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

Compute service (nova) instances with ephemeral storage on NFS shares stop working as soon as the containerized Compute agent service restarts on the hypervisor host. That happens because of changed permissions of /var/lib/nova/instances.

*Workaround:* Manually restore permissions to the original values and avoid the service restarts.

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
