Enable Commercial Usage of Master

[rHorsey]

Issue to track requirements for Commercial usage of buildstockbatch. Initial todos:

• OpenStudio version abstraction in base.py through yml
• sys_image_dir abstraction in eagle.py and hpc.py through yml
• Add requests status code check in hpc.py for pulling down singularity container
• Include results directory protection behavior
• Enable custom bundle option in hpc.py for non-linked gems (i.e. OpenStudio Standards)
• Add commercial workflow
• Enable precomputed sampling
• Ensure lack of BuildingCharacteristicReport is not a problem

All items above believed to be satisfied by #65 however testing is required (unit & on eagle.)

@rHorsey can we close this issue? ComStock can definitely be run on local docker and on Eagle using the code on master. I haven't tried testing AWS, but IMO that isn't worth keeping this issue over.

Fixed in #238
