Good point, I would add a cli command (or expose a control) to modify the
coordinated activation sequence (on zookeeper) and allow a broker matching it
to correctly start or, the opposite, to allow a broker to match the coordinated
activation sequence and allow it to start as it was the most up to date one (it
seems a better option to me). This is for proper disaster cases eg no brokers
with "right" data available to start

> Assuming a multi-primary set-up, if the broker acting as backup lost quorum,
> is restarted without applying the coordination-id patching on NodeManager:
> if its local activation sequence is > 0 (because of a past sync with the
> other live) the backup succeed to activate, causing a split-brain (although
> its NodeID is a random one vs the original coordination-id).
