Adding capability to run FastFrames from a remote machine and accessing eos files remotely

Goal is to make it easy to access ntuples stored in eos from another machine in condor jobs. In this case, this is tested on the UChicago facility. Changes are made to condor_submit.py and also to produce_filelist.py and produce_metadata_files.py (to add a url to the eos paths in the filelist.txt). The condor_submit.py has a check added to produce the warning that this can cause a lot of traffic between the machine running the jobs and the EOS instance using a function 'checkIsRemoteEosAccess()'.
