Handle HOT when converting Outputs to Attributes
Handle HOT when converting Outputs to Attributes

When converting the Outputs of a provider template into Attributes of its
facade resource use the Template object (which translates the template into
a consistent, cfn-like format) instead of the raw template data, so that
HOT also works.

Also fixed an outdated (and therefore now misleading) comment.
