Adding event selections to B2G offline DQM workflow 

There are three new event selections to add to the B2G offline DQM workflow : 
 - all-hadronic : dijets with pt > 400 GeV, |delta y| < 1.0, |delta phi| > pi/2
 - semi-muonic : "2-d" isolation cut for boosted muons, plus one jet with pt > 400 GeV
 - semi-electronic : "2-d" isolation cut for boosted electrons, plus one jet with pt > 400 GeV
