That's inherited from how the cfn-compatible API does it, but it doesn't 
seem hacky to me. And it matches exactly how the UI works - you upload a 
template, it validates it and gets back the list of parameters.

This raises a good point though - it ought to be Heat that determines 
the order of the parameters and returns them in a list (like heat-cfn 
does - though the list is currently randomly ordered). Clients need to 
treat the template as a black box, since the format changes over time.
