cmssw FastGenParticleCandidateProducer does not exist

The generator step imports PhysicsTools/HepMCCandAlgos/python/genParticleCandidates_cfi.py which uses a module named FastGenParticleCandidateProducer. That name does not appear anywhere else in CMSSW. The module label genParticleCandidates does appear elsewhere in various python files but it is never associated with any other module type.

It appears that all uses of genParticleCandidates should be removed from configuration files.

I'll look into this next. I think if removing https://github.com/cms-sw/cmssw/blob/3a1c8a527b7ee9aa60b520977b7ce2dd0b7f835d/RecoMET/Configuration/python/GenMETParticles_cff.py#L13 doesnt change anything, then it is safe to remove this

Seems fair, but maybe @mkirsano can provide some additional info about this.
