Broker ingress closes connection to rabbitmq to early

[eloo-abi]

Describe the bug
We have seen that the broker ingress will stop the rabbitmq connections but is still accepting HTTP requests.
This ends in a lot of errors during this shutdown phase.

Expected behavior
The ingress stops first accepting HTTP requests (readiness probe?) and stops the rabbitmq connections at the very end of the shutdown

To Reproduce
Send cloudevents using http to the ingress and then trigger a restart of the ingress

Knative release version
1.20.x
