acceptance: switch RDO to CBS repositories

This patch changes the repositories used to install OpenStack Liberty on
RDO by using CBS repositories and RDO trunk.

Here is the RDO roadmap that is suggested if we want to run Liberty:
From now until GA:
http://trunk.rdoproject.org/centos7-liberty/current/
http://cbs.centos.org/repos/cloud7-openstack-liberty-testing/x86_64/os/
http://cbs.centos.org/repos/cloud7-openstack-common-testing/x86_64/os/

After GA:
http://mirror.centos.org/centos/7/cloud/x86_64/openstack-liberty

Note about EPEL: deps from EPEL are rebuilt in CBS, so EPEL could be
disabled in the future.
