Keystoneclient logs auth tokens

[Joel Friedly]

``keystoneclient/middleware/auth_token.py`` contains a bunch of places where auth tokens are logged out. This could be useful for debugging, but log files are the kinds of things that users often forget to secure. We should make them not contain sensitive data.

Could this be resolved with this patch?

@ldbragst I originally wrote the ticket and a patch to fix token logging in ``keystoneclient/middleware/auth_token.py``, but this seems to be fixing essentially the same issue in ``keystoneclient/session.py``. (I didn't realize it was present there.)

I actually meant to have this ticket closed by my review, but it looks like you need to have a "Fixes" clause instead of a "Closes-Bug" clause in the commit message to make that work. Let's just say that patch 99432 resolves this bug.

Closes-Bug should actually work, but unfortunately the bug was targeted at keystone rather than python-keystoneclient.
