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.
Can we keep the alignment the old way, and just align cloud_subnets and orchestration_stack?  The pattern I've been following in the refreshers is to align all the attributes amongst themselves, and then align all the associations separately amongst themselves, even though Rubocop complains.
