Fixed bug in get_schedds_via_condor_config_val menthod
It had extra ticks.  Very seldom used use case where all
3 frontend services sharing same condor location.
Merge branch 'branch_v3plus_igor_2454_v2' for #4657
Merge branch 'branch_v3_2'
4694: Fix typo in condor_startup for check_only (affects debug_mode)
4697: Properly escape parameters in factory for submit

In v2, we escape parameter values since they get submitted as
command line arguments to condor_submit.  This was missing in v3.
Merge branch 'v3/4697' into branch_v3_2
