Ubuntu source has old rbd package

[Niklas Hagman]

I have a ceph deployed with "ceph-ansible" using branch stable-4.0. This means for most installation Ceph Nautilus 14.2.4+ is installed.

In Kolla-ansible 8.0.1 with kolla_install_type source and kolla_base_distro ubuntu, librbd1 and python-rbd is 12.2.12-0ubuntu0.18.04.3.

This makes OpenStack unable to communicate with ceph after following the guide at https://docs.openstack.org/kolla-ansible/stein/reference/storage/external-ceph-guide.html because ceph.conf has bracketed format on mon host line.

Example:
mon host = [v2:192.168.39.12:3300,v1:192.168.39.12:6789],[v2:192.168.39.17:3300,v1:192.168.39.17:6789],[v2:192.168.39.19:3300,v1:192.168.39.19:6789]

This is not supported in librbd1 12.2.12-0ubuntu0.18.04.3.

It seems like this is about to be fixed with https://review.opendev.org/#/c/690507/
Am hearing 14.2.2 will land in Train release. Correct?

It sounds like we need better documentation of which version of Ceph is included in our images. I'm not sure it's a bug, just a compatibility issue between the version of ceph you deployed and the version of rbd in our images.
