rabbitmq image pulled from dockerhub

[acancell-redhat]

The manifests referring to rabbitmq currently does not mention any registry in the image name, therefore by default dockerhub is used, risking to hit the dockerhub pull limit.

A registry might be explicitly used in the image name selection, in order to use an alternative registry without a pull limit.

Example of a current workaround:
grep -r 'rabbitmq:3.11.19-management' | awk '{print $1}' | tr -d ':' | xargs -I {} sed -i 's%rabbitmq:3.11.19-management%public.ecr.aws/docker/library/rabbitmq:3.11-management%g' {}
