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 References #71
