Further integrations in the HLT Run2 menu

This PR includes (and therefore can supersede):
- #4823: More run2 HLT configs
- #4851: HLT updates for Run2: CMSHLT-84 exotica dimuon triggers for run2
On top of it, it allows the BPH paths of CMSHLT-82 in the GRun menu, and the "HZZ2l2nu Photon + Jet Control trigger menus" of CMSHLT-83 in the FULL menu (they will be promoted to the GRun subtables only when the corresponding DQM/Validation modules will be also provided).

The FastSim signature needed is the same as from the other two PR's, and relates to HLT customizations for FastSim
