Update to rabbitmq/amqp091-go

[gabo1208]

Hi folks! We currently use this library in Knative. Specifically in this project: https://github.com/knative-sandbox/eventing-rabbitmq and we are thinking to update the AMQP client library from streadway/amqp to rabbitmq/amqp091. Is that something you'll consider upstreaming?

Here i'll leave the PR: #52 with the current changes that we have (we are using a fork from this site there to implement some extra things we needed)

Blocked until we decide what to do with Wabbit
