tox is failing because oslo.messaging 9.1.1 installs kombu 4.6.7, which
requires amqp >=2.5.2, but it is pinned to 2.5.1. Additionally, the
deckhand-integration-docker are failing because barbican is not being
deployed correctly.
This change updated the pinned version of amqp to 2.5.2, and uses the
barbican deployment script in openstack-helm.
