In a follow-up PR, I'd like to consider breaking ceph_bootstrap_deployment.sh into two scripts:

The first one, called "ceph_bootstrap_prep.sh" would end with this version information. Sesdev would take the "cephadm" and "ceph-bootstrap" versions and check that they are compatible. Then (and only if the versions are not known to be incompatible) it would run the second part, "ceph_bootstrap_deployment.sh", which would just trigger ceph-bootstrap deploy and possibly the qa tests.

do we need a cephadm --version?

[smithfarm]

It's a good idea to have one, but it's not needed for this PR because cephadm is not installed at this point. (It gets installed by ceph-bootstrap deploy)
