condor: fetch & create condor dirs from config

Updated the condor plugin to fetch and create all condor directories
from the config using condor_config_val.
condor: set SCHEDD_NAME on each host

This is needed in versions of condor > 7.7.2 - without this condor_q

allows the same config to work on condor 7.7.2 and 7.8.2.
