Condor fixes

[dpryan79]

These modifications to the HTCondor job runner put it in line with the DRMAA job runner and fix this issue on the trello board. In short, the runner now looks for an appropriate embed_metadata_in_job param in job_conf.xml. If it finds it and the value is False, then metadata will be set locally after a job has successfully finished. If the value is True or the parameter doesn't exist, then the default is to have the remote node attempt to set the metadata.

For my own use, it would be more convenient for embed_metadata_in_job to default to False, but since the other job runners default to True it's probably best to keep things the same.

👍 This seems like a fine workaround until Galaxy becomes more competent at metadata handling - Pulsar and the local job runner have similar configuration switches.
