This pull request is fully signed and it will be integrated in one of the next CMSSW_10_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_10_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
