Fix revoking domain-scoped tokens

A token scoped to a domain wouldn't be revoked for a domain-wide
revocation event. This is because the code to convert a token to a
dict for revocation event processing didn't handle domain-scoped
tokens.

Add a test for revoking a scoped token from an unscoped

There was no test that showed that when a scoped token created from
an unscoped token is revoked that the unscoped token also winds up
being revoked.

Don't override tox envdir for pep8 and cover jobs

infra's run-pep8 and run-coverage jobs assume the envdir for pep8 and
cover jobs are not overwritten, so it can call out to .tox/pep8/bin/pip
and .tox/coverage/bin/pip respectively.

This bug is causing keystone pep8 and coverage jobs to occasionally fail
in the gate.

If the motivation behind overriding the envdir jobs to use venv, one can
use devpi and/or wheels to speed up the process of building a venv.

Remove debug CADF payload for every authN request

Since we already provide a generic mechanism for logging notifications
(setting the notification_driver value to 'log'), having an additional
debug log just for this case seems unnecessary.

Do not override venvs

OpenStack infra jobs assume the virtual environments are setup in
a specific way. Do not override the virtual environments in any
tox target.
