Check resources are in expected states

Allow resource to check whether it is in an expected state and update
status and action accordingly.

This adds a check action to the stack that will perform checks in all
their resources and nested resources as well.  If a resource doesn't
have a handle_check() method, check for that resource will just pass.

If any resource at the end of a Stack.check() doesn't have a
handle_check() method, then a message will be added to the status_reason
of both the resource and the stack saying that CHECK is not (fully)
supported.  This allows for the other resources to implement their own
checks for their expected states.
