This pull request is fully signed and it will be integrated in one of the next CMSSW_12_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_3_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)

• Update of the test script is needed in view of the ConfDB policy of deleting Candidates GTs older than 6 months
• Not clear whether it needs to stay in the release, but it can be merged anyhow just in case another 12_0_X release will be built
