Add --setup option in hltGetConfiguration

[silviodonato]

This PR adds the --setup option to hltGetConfiguration. It may be useful for the HLT developers.

Example-1:
hltGetConfiguration --full --offline /users/sdonato/TriggerVBF2 --setup mysetup_cff.py > hlt.py
is equivalent to
hltGetConfiguration --full --offline /users/sdonato/TriggerVBF2 > hlt.py
and adding
process.load("mysetup_cff")

Example-2:
hltGetConfiguration --full --offline /users/sdonato/TriggerVBF2 --setup /dev/CMSSW_9_0_0/HLT > hlt.py
is equivalent to
hltGetConfiguration --full --offline /users/sdonato/TriggerVBF2 > hlt.py
hltConfigFromDB --cff --configName /dev/CMSSW_9_0_0/GRun --nopaths > setup_dev_CMSSW_9_0_0_HLT_cff.py
and adding
process.load("setup_dev_CMSSW_9_0_0_HLT_cff.py")
