More CSC performance measurements from run II data

The endcap muon detector of CMS is composed primarily of Cathode Strip Chambers (CSCs). In run II of LHC, the CMS experiment has collected data from pp collisions at 13 TeV centre-of-mass energy. This document augments CERN-CMS-DP-2015-053, which includes measurements of the efficiency of the CSC system to provide reconstructed muon track segments, by adding the efficiencies for the CSC system to provide trigger primitives for the CMS Level-1 Muon Trigger.
