This pull request is fully signed and it will be integrated in one of the next CMSSW_13_0_X IBs (but tests are reportedly failing) and once validation in the development release cycle CMSSW_13_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
