keystone middleware was named incorrectly
don't load keystone auth_token middleware twice

The load in the [keystone] section was attempting to use the default
value for the signing_dir, which was /root/keystone-signing) since there
was no 'signing_dir =' statement in that section.
We only need to load it once

Renamed enamed the keystone filter to keystoneauth for consistency
with the docs

Set signing_dir to /var/cache/swift as per docs
create signing_dir with correct permissions
