Allow Ceph pools to use 1x replication

Beginning with the Pacific release, Ceph pools are not allowed to
use 1x replication by default. This is problematic for the
openstack-helm gate scripts, which frequently use 1x replication
for automated testing. This change adds Ceph configuration and
command overrides to allow those gate scripts to continue to use
1x replication for testing.
