From a openstack/requirements POV we have a couple of options
https://review.openstack.org/#/c/392245/ (uncap amqp) https://review.openstack.org/#/c/392135/ (cap kombu)
The first option is better as we're trying hard to *NOT* have caps where we can and it removes one :) However amqp was capped in https://review.openstack.org/#/c/322484/ because kombu itself required amqp < 2.0 https://github.com/celery/kombu/blob/3.0/requirements/default.txt
With the release of 4.0 we can see that the inverse is now true: https://github.com/celery/kombu/commit/b48a887a865971f98f3913c24daeb64e9db52527
So it seems to me that altering the cap on amqp is the correct solution here.
