Complete implementation of OVA handling 

Add functions for uploading, listing, and removing OVA images to the API
and CLI interfaces. Includes improved parsing of the OVF and creation of
a system_template and profile for each OVA.

Also modifies some behaviour around profiles, making most components
option at creation to support both profile types (and incomplete
profiles generally).

Implementation part 2/3 - remaining: OVA VM creation
