Update of the MVAMET algorithm plus use of new training files

[mmarionncern]

Update of the MVAMET algorithm + use of new training files :
The RECO/miniAOD sequence is untouched by the changes of the mva MET algorithm: no expected changes in term of performances/contents at the RECO level

Performances of the MVA met are better than with the previous version of the algorithm and the previous training.
Corresponding training files are updated in :
cms-data/RecoMET-METPUSubtraction#2

Test files have been updated as well.

For #9333 f5ce07b

Updating of the MET MVA algorithm. The Reco and Mini-AOD sequences are untouched by these changes. #9378 is the matching 74X version of this PR.

The code changes are satisfactory, and Jenkins tests against baseline CMSSW_7_5_X_2015-06-06-2300 show no significant differences, as expected.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs unless changes (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
