Detailed Resource Show

After creating a stack, there is currently no way to retrieve a
resource's attributes other than outside of heat (e.g. a user can get
the ID of a nova server and call nova directly to get such attributes).

We propose returning all resource attributes when displaying data for a
specific resource and also adding options to retrieve dynamic attributes
as well. This way, a user will be able to issue a resource-show call and
be able to look up attributes after creating their stacks even if the
template author didn't think about them beforehand.
