    Set affinity to 1 for OpenStack-CI gate checks

    This change sets the affinity for the RabbitMQ, Galera, Repo, Keystone and
    Horizon containers to 1 when running on OpenStack-CI. The intention here is
    to reduce the number of failures we see within the gate due to resource
    starvation.

    This patch is specifically only going into the master (Liberty) branch as
    this is the only place where resource starvation has become critical. This
    patch is a holdover until the current gate check design is revised after the
    Liberty release. The redesign will split the current monolithic gate check
    into multiple use-cases which each use less resources. This is described in
    https://review.openstack.org/221009

Change abandoned by Jesse Pretorius (<email address hidden>) on branch: kilo
Review: https://review.openstack.org/264887
Reason: This is unnecessary as the issue has nothing to do with resource constraints.

A whole bunch of work has gone into the Mitaka cycle in order to resolve this: https://review.openstack.org/#/q/project:%255Eopenstack/openstack-ansible.*+topic:gate-optimise

As more options for optimisation are found, they will continue to be added.
