Remove old parsoid deploy repos and remove parsoid salt module

It seems at some point the parsoid module was removed from the
repo, but wasn't removed from the salt config. The missing
module breaks the module/grain/pillar refresh across
the cluster. This change cleans that up and removes any reference
to it (which removes the old parsoid deploy repos).
