The changes in this PR are introducing a the new class in replacement of an existing one; it looks like only the 'private' L1T workflow have been adapted for this replacement, while all of the consumer code ( HLT?) has not been touched. This is obviously ok until you don't need updates on the existing tags ( implemented with the old class ). What is the plan/intention for this?

@ggovi Changes in the GlobalTrigger on which the Offline worflows would depend need changes (changes of ints to floats, etc). Work is started on this by the L1T GlobalTrigger experts.

This pull request is fully signed and it will be integrated in one of the next CMSSW_11_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
