Adding a vertex smearing configution for pp at 5 TeV, based on latest info from the LHC

[mandrenguyen]

Expected beam conditions for the pp run at 5 TeV that will take place in about 4 weeks.
The GEN-SIM production will be in the same release used for 13 TeV, so I will also add this into 71X.
I can also add this in CMSSW8, if we're no longer forward porting from 76X.
As usual, we will iterate with ppd/pdmv to get the matching reco BS in the GT.

Adding a vertex smearing configution for pp at 5 TeV, based on latest info from the LHC

It involves the following packages:

Configuration/StandardSequences
IOMC/EventVertexGenerators

@mandrenguyen , is "Expected" an optimal name? before "Nominal" was used for 13 TeV.

[mandrenguyen]

@civanch Makes sense. Will update in a bit.

Comparison is ready

There are some workflows for which there are errors in the baseline:
4.53 step 3
25.0 step 4
1330.0 step 4
1001.0 step 3
The results for the comparisons for these workflows could be incomplete
This means most likely that the IB is having errors in the relvals.The error does NOT come from this pull request

@mandrenguyen , likely similar PRs for 7_1 and 8_0 are needed

[davidlange6]

@mandrenguyen - do we really need to keep around the last "new" HI beamspot? (ie, can we just change it as its now seemingly obsolete)

@davidlange6
We had intended to update the HI beamspot to something more realistic after it become clear the centroid wasn't really going to be at the origin, but in the end decided not to restart the GEN-SIM for that, as the real data may turn out to be different from both. If it's not hurting anyone, I would leave it around (it's not active in relval) for systematic studies. If nothing else, I can always overwrite this with the real beam parameters after we actually see the data. If it really bothers you, I can zap it, preferably as a separate PR.

[civanch]

please test
@mandrenguyen , do we still need this PR?

@civanch GEN-SIM will be in 71X. Not sure we'll ever run this in 76X, but I put it in just in case.
