Backport of new pileup jet ID for MiniAOD re-processing

[ahinzmann]

Backport of the following PRs:
#10398 jbrands:newOfflinePuID_new
#10730 ahinzmann:fixpuid
#10625 ahinzmann:PUjetIDcleanup76
#10923 ahinzmann:pileupjetiddqm76

They contain a new training of the pileup jet ID with 74 MC.
This is not the final/optimal training, but already better than the 53 training on 74 MC (ROC curves are in #10625). Optimization of a working point for MVAmet is also not yet done, thus it is not configured to be used in MVAmet.

runTheMatrix -l limited works in CMSSW_7_4_10_patch1

@gpetruc this can be included in the MiniAOD processing

@slava77 maybe this needs another triggering of tests, since I included one commit a minute after the test was requested

[slava77]

@cmsbuild please test

[cmsbuild]

The tests are being triggered in jenkins.

This is backport from 76X PRs which are already approved.

for #11007 e00bc47

• backport contains changes from the 76X PRs as described
• jenkins tests pass and comparisons with baseline show differences only in DQM plots in cleaned jets and in PU-ID variables, as expected (monitored RECO products are unchanged)
• the list of products stored in RECO/AOD output and their size is unchanged

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_4_X IBs once checked with relvals in the development release cycle of CMSSW (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
