What is the content difference between them? IIRC daemon-base has *just*
packages installed, while ceph/ceph has all the bash scripts needed by
ceph-nano and ansible.. is that still the case?

Can we simplify all of this to have a more consistent/streamlined
approach, and/or reduce the # of images? It seems like we could have just
2 images:
ceph/daemon-base -- just the daemons + packages
ceph/ceph -- daemon-base + the extra scripts (just for compat w/ existing users)
and then have tags like
v14 - latest nautilus
v14.2 - latest stable nautilus (same as above unless we are pre-release)
v14.2.3 - specific point release
and then also
v14-tip - latest dev branch (daily)
...although the latter could actually come from quay.io/cephci if we fix
the stupid ceph-build issue that is making it *only* build containers for
wip-* branches. In cephci, there'd be tags like
nautilus
octopus
wip-foo-bar-baz-$date-$distro-$arch-devel
When ceph-container.git updates, we could either do nothing or push a big
button to rebuild everything? I'm unclear on how often older images
need to be rebuilt...
