Quorum Queue support for RabbitMQ dynamically.

[sonicboom15]

Describe the feature

RabbitMQ on version 4.0.0 onwards has deprecated classic queue mirroring.

Classic queue mirroring is used to ensure high availability queues on clusters so that even if one or more servers go down the cluster can still operate without any data loss.

RabbitMQ team now recommends using Quorum queues as a replacement instead of setting up classic queue mirroring.

We use dapr in production and when we were looking into an update for our RabbitMQ nodes. We came to realise that quorum queues are the only way which can help us achieve queue mirroring across nodes to ensure its durability.

Dapr already has partial support for Quorum queues provided we create a subscription component declaratively, but this wouldn’t work for queues created dynamically.

Dapr Quorum queues docs : https://docs.dapr.io/reference/components-reference/supported-pubsub/setup-rabbitmq/#use-quorum-queues

RabbitMQ classic queue mirroring : https://www.rabbitmq.com/docs/3.13/ha

One suggested approach to the use of a defaultQueue field in the pub sub component allowing the use of different types of queues dynamically for RabbitMQ.
