synchronize HLTTrackerHaloFilter to the edmNew::DetSetVector<SiStripCluster>

as discussed in this hn thread
https://hypernews.cern.ch/HyperNews/CMS/get/hlt/3500/1/1/1/1.html

recent developments done on the edmNew::DetSetVector<SiStripCluster>
need to be propagated to few modules which are still using the no more supported edm::RefGetter<SiStripCluster>

the involved modules are
- HLTTrackerHaloFilter (used by the HLT_BeamHalo path)
- SiStripMonitorMuonHLT (which is somehow obsolete and actually never gone in production)
