Cephfs tests were disabled in order to merge
https://review.opendev.org/695568 due to gate failures that were
blocking it. CephFS isn't used in openstack-helm-infra, so it
wasn't required for that work. This change re-enables the cephfs
tests so we can work through any issues that are causing further
failures.
Since the the issue got fixed in 14.2.8 , upgrading all daemons to 14.2.8.
