    Make outward_rabbit pre-checks idempotent

    Copy the patterns from the rabbit checks, skip some pre-checks when the
    container has already been started. Without this change the pre-checks
    fail when you re-run the deploy, i.e. the port is not free because
    rabbit is already running on that port.

    This bug was triggered because murano is enabled, and this change has
    been added to add the extra rabbitmq instance by default:
