Open Stack

The latest release of reno tries to add anchors to the page in a way
that ensures they are named consistently across builds. For projects
with the same version number in multiple series (which can happen for
non-milestone projects that haven't tagged for rocky yet), this causes
duplicate anchors and causes the release notes build to fail.

There is a fix for this in https://review.openstack.org/564763 and we
will try to get a new release of reno out as soon as that patch merges.
