[PATCH] ovirt driver: support user-level API

[Oved Ourfali <oo...@redhat.com>]

This patch contains the necessary changes to support the oVirt engine
user-level API.

The current way of configuring that is to use the API_PROVIDER
environment variable:
1. API_PROVIDER="http://server:port/api;;USER" - User API (no DC-id)
2. API_PROVIDER="http://server:port/api" - no DC-id, Admin API
3. API_PROVIDER="http://server:port/api;dc-id;USER" - User API (dc-id is
ignored by rbovirt)
4. API_PROVIDER="http://server:port/api;dc-id" - Admin API working in a specific
DC scope
