Comment 4 for bug 1959674

To have that said, other projects like cinder that have common usecase with barbican, just pass context and don't produce extra token: https://opendev.org/openstack/cinder/src/branch/master/cinder/volume/volume_utils.py#L1018-L1019

However when I tried same approach with octavia and used castellan RequestContext this changed nothing and same stack trace is produced from keystone side.
