Bug description:
  [Impact]
  ceph-volume tool is non-functional in proposed updates for Ubuntu 24.04 (19.2.0~rc2-0ubuntu0.24.04.1).

  
  [Test Case]
  sudo apt install ceph-volume
  sudo ceph-volume -h

  
  [Where things could go wrong]
  The upstream proposed fix has not yet been accepted and the patch does increase the code complexity in this area; fix has been tested in PPA prior to upload to reduce risk.

  
  [Original Bug Report]
  ceph-volume fails with an AttributeError, cf. below.

  I believe this might be due to importlib_metadata removing deprecated
  shims:

  metadata.readthedocs.io/en/latest/history.html#v5-0-0

  ```
