PYCICLE_GITHUB_WHATEVER vs PCYCILE_WHATEVER design

[PDoakORNL]

There is a bad smell around PYCICLE_GITHUB_BASE_BRANCH & PYCICLE_BASE
Just seems like a potentially disasterous alias for PICYCLE_BASE or vice versa
as far as I can tell they are set equal here and that's that. Could be for the others as well. Seems like the intention was to decouple the PYCICLE_GITHUB values from those passed to the CDash dashboard. But then GITHUB_ORG and GITHUB_PROJ are reused.

What about treating all variables/defines coming in from cmake configs as a dictionary with keys that are the cmake variable names. Most could just be carried straight across to the dashboard call.
