The fix to allow global requirements changes to land in stable/liberty
is in https://review.openstack.org/235924

After that has merged, https://review.openstack.org/233854 will block
oslo.messaging 2.6 from stable/liberty.

Then we have https://review.openstack.org/235815 to strip the
pre-versioning setting and fold in the requirements updates for
ceilometer.

We need to land the patches in that order.

Releasing 2.6.2 would also be OK, if that happens first.
