Ironic Python Agent now supports using a proxy for downloading user images. Steps for enabling this functionality for the Bare Metal Provisioning service must be documented. See http://docs.openstack.org/developer/ironic/drivers/ipa.html?highlight=proxy#using-proxies-for-image-download-in-agent-drivers for an upstream example.
Assigning to Sandra for review.
