Make jigs even more late-bound. [5/5]

This pull request series makes jigs even more late bound, and reworks
how roles are defined and loaded from crowbar.yml to make it a
seperate section from the to-be-written jigs section, as the jigs
section should concern itself with declaring what (if any) jigs a
barclamp provides.
