[ENHANCEMENT] Apply RabbitMQ classic queue version 2

[quantranhong1999]

Claimed to be better than version 1 cf:

• https://www.rabbitmq.com/blog/2023/05/17/rabbitmq-3.12-performance-improvements#classic-queues-massively-improved-classic-queues-v2-cqv2
• https://www.rabbitmq.com/blog/2023/05/17/rabbitmq-3.12-performance-improvements#312-cqv1-vs-cqv2

Before (all classic queues v1)

After (all classic queues v2)

Better performance overall (p99 805ms vs 914ms).
SELECT p99 1874ms vs 2049ms
UNSELECT p99 1420ms vs 1755ms

Could you please...

Start a james prior this cange and queue one
Stop it, remove it
And start a james after this change and with queue 2

IE ensure this is not a breaking change.

Thanks!

IE ensure this is not a breaking change.

Sadly this is a breaking change (queue purge is needed).
I would add a configuration to avoid this breaking change e.g. for the older James versions.
