This can be automated to don't add the extra info to the release in case of a
tag creation, but that means that you have to run all the testing again when
pushing the tag, ideally it would block the tag creation, so if it fails it
would not tag the build but we don't have any gating system so right now it
would have been done after the tag is pushed, so you'd have to force tag again
(creating rpms with the same version that contain different code) or bump the
tag (making it feasible that the first released version is not the lowest tag,
for example, that the first release 4.17.* vdsm to be 4.17.5 instead of 4.17.0
because it took 5 retaggings to pass the tests)

Extra metadata can be added to the rpm:
branch: master
commit_id: 7428372

so the build passed QE and
1) file names of the rpms can be changed to standard NVR
2) createrepo is running
3) repo is validated repoclosure
