This looks good now. I have tested it for various existsing PRs and cms-sw/cmssw#43552. I will merge it tomorrow morning

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next master IBs after it passes the integration tests. This pull request will now be reviewed by the release team before it's merged. @antoniovilela, @rappoccio, @sextonkennedy (and backports should be raised in the release meeting by the corresponding L2)

[smuzaffar]

There are too many commits so I will squash and merge this PR
