TLRs for run2 data processing configurations (start from CSC) backport of #4396 

RecoTLR.py functions to modify the prompt and express processing for run2 detector.
These come with new DataProcessing scenarios (based on config builder pp and cosmics scenarios).
Aiming for July global runs.

Can be tested by calling the regular T0 cmsDriver versions of these (see e.g. 1000.0 or 1001.0) Configuration/DataProcessing/RecoTLR.customisePromptRun1 and Configuration/DataProcessing/RecoTLR.customiseExpressRun2 for pp or Configuration/DataProcessing/RecoTLR.customiseCosmicDataRun2 for cosmics.

some plots for amusement are posted in #4396
