Option to install FreeIPA

Option to setup FreeIPA server and join hosts into IPA. If also SSL for
AMQP or Horizon is enabled it gets all certificates from freeipa.

Currently experimental and unsupported option. Joining FreeIPA domain
requires change of resolver on hosts and mod_ssl colides with mod_nss in
case of running FreeIPA server on Controller node thus making allinone
setup difficult.

Requires: redhat-openstack/openstack-puppet-modules#244
Change-Id: I84e0dee07bf3a4066350a66aebb45678a9a316ba
Closes-Bug: rhbz#903645
