Phase2 tracker (BE5D) + extendedPixel up to eta=4 

Files from @atricomi 

First attempt to add the extended pixel phase2 tracker geometry (new geometry)  in the release.

I'm providing here the recipe  (up to GENSIM):
cmsDriver.py FourMuPt_1_200_cfi --conditions auto:upgradePLS3 -n 10 --eventcontent FEVTDEBUG --relval 9000,300 -s GEN,SIM --datatier GEN-SIM --beamspot Gauss --customise SLHCUpgradeSimulations/Configuration/combinedCustoms.cust_phase2_BE5DPixel10D --geometry ExtendedPhase2TkBE5DPixel10D  --magField 38T_PostLS1 --fileout file:step1.root

the recipe is not configured in runthematrix at this stage, but it seems that nothing already configured is broken or affected by this new geometry  (tested with  runTheMatrix.py --what upgrade -l 3300,4400 )
