Provide pretty status bars to indicate upload progress for tasks that
perform large file uploads to the API ('provisioner ova upload' and
'storage volume upload') so the administrator can gauge progress and
estimated time to completion.
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
Move all API calls to a new common function called call_api to
facilitate easier future changes. Use this function to implement API key
handling via request header value as well as integrate the request URI
generation and debug output handling.
