It is super frustrating to have to install all of Keystone just to get this one piece of code. As this middleware is just a client, I am proposing we move it into the existing keystone client library - python-keystoneclient. What are the immediate feelings here?

A general principle I have for Python packages is that 'optional'
things should be separate packages: there is some overhead, but its a
lot simpler when it comes to determining distribution dependency
rules, because you can rely on the Python dependency metadata.
Creating multiple binaries from one Python source package is only
needed when this principle is violated :).
