Description of problem:
A RESTful smart proxy is needed in order to support provisioning of IPA hosts from a Foreman. This will be an unauthenticated REST server which will be able to manage hosts and hostgroups in an IPA server.

IPA design: http://www.freeipa.org/page/V3/Smart_Proxy
Closing the bug, instead of developing the Satellite proxy on our own, we will work with Satellite team on improving their native proxy capable of handling IPA. See https://bugzilla.redhat.com/show_bug.cgi?id=1084136#c49 for details.
