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.
Should stack_id be in the data anywhere?  This one is interesting because the uid is different than the "uid" of the template because of the md5 stuff...maybe we should md5 it here too?
