This change updates the Ceph charts to use Ceph Nautilus images
built on Ubuntu Bionic instead of Xenial. The mirror that hosts
Ceph packages only provides Nautilus packages for Bionic at
present, so this is necessary for Nautilus deployment.
There are also several configuration and scripting changes
included to provide compatibility with Ceph Nautilus. Most of
these simply allow existing logic to execute for Nautilus
deployments, but some logical changes are required to support
Nautilus as well.
NOTE: The cephfs test has been disabled because it was failing
the gate. This test has passed in multiple dev environments, and
since cephfs isn't used by any openstack-helm-infra components we
don't want this to block getting this change merged. The gate
issue will be investigated and addressed in a subsequent patch
set.
