There seems to be some inconsistency around whether Keystone endpoints
in the catalog should be versioned or not. Specifically, should they

I did a survey of code using keystone-manage bootstrap via codesearch:

* puppet-keystone: unversioned
* Keystone install guides: versioned
* OSA: unversioned
I imagine that when v2 was around, the endpoint needed to be

I tested using Stein and Train U-C. The former fails, the latter
works. If I use Stein U-C, then update keystoneauth1 to 3.17.3 (from
Train U-C), it works.
