Update Run2 reco geometry, new SLHC reco geometry


I would like the three files (cmsGeom10.root, cmsGeomRun2.root, and cmsRecoGeom2019.root) to be integrated in the following releases:
7_1_X
7_2_X
6_2_SLHC_X

I  know it is not trivial to integrate this in CMSSW 7x and SLHC releases. Let me know if I can make this any easier.

Thanks,
Alja
