[Dominic-Stafford]

PR description:

Update of Herwig 7 interface to allow update of Herwig 7.1.4->7.2.0, and reintroduced cmssw/Configuration/Generator/python/TT_13TeV_Pow_Herwig7_cff.py, which is needed for workflow 535, but seems to have been removed

PR validation:

Has been tested with runTheMatrix workflow 535, and the test commands on the Herwig twiki

If this PR is a backport please specify the original PR and why you need to backport that PR:

First part is a backport of #29523 to allow use of Herwig 7.2 for 2017 production

This pull request is fully signed and it will be integrated in one of the next CMSSW_9_3_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo (and backports should be raised in the release meeting by the corresponding L2)
