Review comment:
I sent a commit as an attempt to remove the mirrorID and just use
another value with the node UUID. it will be another Object and another list,
but it will work.
right now things are not 100% working as I'm getting some reflection on the
test cases (sends happening again after the mirror is sent).. I will fix this
tomorrow...
the last commit still a WIP and a lot of that will still change.. I sent to
the PR just a reference of my attempt.

> Enhance AMQP Mirror support with dual mirror
> --------------------------------------------
>
> Key: ARTEMIS-3243
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3243
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.17.0
> Reporter: Clebert Suconic
> Assignee: Clebert Suconic
> Priority: Major
> Fix For: 2.18.0
>
> Time Spent: 8h 10m
> Remaining Estimate: 0h
>
> at the current Mirror version, we can only mirror into a single direction.
> With this enhancement the two (or more brokers) would be connected to each
> other, each one having its own ID, and each one would send updates to the
> other broker.
> The outcome is that if you just transferred producers and consumers from one
> broker into the other, the fallback would be automatic and simple. No need to
> disable and enable mirror options.
