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.
I am using a dedicated stack, although it is named cloudformation-spec, and its child stack is auto named as cloudformation-spec-WebServerInstance-QS899ZNAHZU6
