Refresh aws cloudformation

This the second half from the slitting of PR #333. It is a sub PR of #523.

This PR collects templates and stacks and updates manageiq database. 

It depends on PR #899: add_orchestration_models. New changes are in the second commit as the first commit is for PR #899.
This should return the exact thing that is in ems_ref.  Since we are calling .to_s it should be done here.  This is the reason I set a uid variable in most of the methods...to be sure it's consistent.

Additionally, can you put ems_ref second after type (again, for consistency across these parse_* methods).
