Subject: src/common/version: append vendor release to ceph version(s) output
X-Git-Tag: v21.0.0~135^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=541439b290001e1bb15dc9b2b40671671c2b85c4;p=ceph.git

src/common/version: append vendor release to ceph version(s) output

Introduce a build-time mechanism to allow vendors or downstream
distributions to append their release/version metadata to the output of
ceph version and ceph versions.

The release string is read from the file `/etc/ceph_version` and appends
it to the version string as `release <value>`. If no value is supplied
or the file is empty, the version output remains unchanged.

Example:
If the `/etc/ceph_version` file has "8.1.0" as string then,
ceph version 8d7daada90 (98d7daada90c6585c6724f69793e804a5e23cb24) tentacle (dev - Debug) release 8.1.0
