tracking client migration

this PR takes into account and improves PR https://github.com/cms-sw/cmssw/pull/5647
(=> PR 5647 might be closed ...)

here the new 2 strip FEDs MEs are handled by strip job (this is needed by strip and tracking client @p5)


moreover, there is --finally-- the migration to DQMHarvester of the DQM/TrackingMonitorClient package
should this line remain uncommented?
