This version of runthematrix has been used to submit :

https://hypernews.cern.ch/HyperNews/CMS/get/dataopsrequests/5863.html

The usual numbering is not changed, pu scenarios are added on top of the existing ones.
To test the PU sequence, the  numbers ar 152xx for shashliknotaper and  150xx fo HGCAL (v5 version) -
Using the option -i all will use old gensim (recycling) 

I also took the opportunity to change the priority of relvals (in MatrixInjector) to a value allowing more flexibility in prioritizing the relval WFs.
