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.
Is this a number or a String?  If it's a number, be sure to put .to_s on the end.  This is because the save_inventory piece tries to compare number (from the Hash) to a string (from the database) and doesn't find a match which causes the records to all get removed and readded instead of just updated.  You may want to put a .to_s on the end here anyway just to be explicit, especially if something changes in the future.
