porting 2017 scenario in 74X : first round of changes

[boudoul]

This PR is starting to port the 2017 scenario in 74X - this PR is not pretending having done all the work (far from that :-) ) , but this is to start it.
I have aligned cmsExtende2017 scenario with the last version of 62XSLHC.
I have added the missing xml files used int his scenario which were only in 62XSLHC.
The algorithm DDHCalEndcapModuleAlgo used in the new xml files is also ported.
Nothing used in any of the standard workflow for run1/run2 is touched.
@bsunanda : you may want to follow this as well

@boudoul - so far this does not affect current Hcal in 74x.
