changing from PXBDetId/PXFDetId to TrackerTopology in CondTools

Replacement of #5646 based on CMSSW_7_3_X_2014-10-09-1400
Since this is in 73x which has moved to the new conditinos by default, I would strongly suggest to use them in your tests as well. To do so, use:
process.load("Configuration.StandardSequences.FrontierConditions_GlobalTag_condDBv2_cff")
instead of:
process.load("Configuration.StandardSequences.FrontierConditions_GlobalTag_cff")
and remove the "::All" from the names of the GTs.
