[pve-devel] [PATCH v1 pve-manager 2/8] ceph: tools: update Ceph version regex

[Max Carrara]

Make the regex more maintainable declaring it as a variable, breaking it
up and commenting it by using the x flag.

Also remove the part that parses our Debian revision (e.g. -pve1) from
the version, as we do not actually include that in our Ceph builds.

The part of the regex that parses the build commit hash is made
mandatory (remove '?' after its group).
