Description of change
Spawns consensus startup asynchronously so it no longer blocks the other
node components during validator bring-up. The consensus handler is now
created before the authority starts (so it is listening for committed
sub-dags first), and the replay-waiting mechanism is rewired from holding
an
Arc<ConsensusAuthority>to receiving theCommitConsumerMonitorovera broadcast channel. A
DISABLE_REPLAY_WAITERenv var is added as anescape hatch.
Built on top of #11850 which is required to prevent OOM on recovery.
