optimized muon validation
fix
DQMStore: remove spurious cout
re-introduce replaces which force DQM in production (in place of DQMio)
introduce --revertDqmio=yes/no to switch back to pool DQM in configuration sent to wmcontrol (DQMIO is untouched if chosen for local workflows)
switch back to use associator for track validation
fix of indentation bug (thanks to Giulio and Shahzad for spotting, seee #2695)
