template for QCD bin for 71X campaign

This is the first fragment for the QCD request in pt bins, created following the example of the min-bias template (I'll use this fragment as basis to prepare all the requests and then upload the rest of the fragments for the other bins at once). Please, check carefully that I implemented correctly the gen guidelines for this campaign (in particular I remove the 'Tune:pp 5', 'Tune:ee 3' options, as my understanding is that all the options regarding the new Tunes are taken from Pythia8CUEP8M1Setting)
