optimized muon validation
fix
DQMStore: remove spurious cout
adding lumisToProcess parameter
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)
fix of indentation bug (thanks to Giulio and Shahzad for spotting, seee #2695)
