[WIP] Batch related functions separed to a module

[kjvbrt]

Submitting to HTCondor goes through fccanalyses submit sub-command instead of being indicated in the analysis script file as an attribute. The change is done to be able to facilitate other providers (Slurm, GRID,...) and other styles of running (Histmaker) in the future.

This PR:

• Introduces new sub-command fccanalysis submit
• Removes ability to submit to HTCondor using runBatch or run_batch attributes in fccanalysis run subcommand
• Adjusts the way how script parameters are provided on the command line, all parameters which needs to go to the script will need to be provided after "--" (double dash).
