RabbitMQ integration tests fail when running in arm64 env

[dadjeibaah]

It looks like we can't run the RabbitMQ integration tests in an arm64 environment.
We might need to update the rabbit-client image to one that has an arm64 build.

It looks like the current rabbitmq client docker image does not have an arm64 build manifest
