backport EtaRangeCaloJetSelector to 71X

Backport EtaRangeCaloJetSelector (PR #4332 from @silviodonato) from 72X to 71X
It can be used for ConfDB parsing in the forthcoming possible 711
Since it is just the definition of a new module, with its python steering configuration, used nowhere in the current workflows, there is no need to wait for possible relvals in 720pre1
