Adds rabbitmq auto provisioning

[PascalSenn]

Summary

Adds auto-provisioning support to the RabbitMQ transport, allowing exchanges, queues, and bindings to be automatically created on the broker at startup.

• Transport-level AutoProvision toggle (defaults to true) with per-resource overrides on exchanges, queues, and bindings
• Endpoint-level AutoProvision inherits from the transport when unset (null)
• Documentation for disabling auto-provisioning in managed infrastructure environments (Terraform, K8s Topology Operator, etc.)

Pull request overview

Adds support for controlling RabbitMQ topology auto-provisioning at the transport level with per-resource overrides, plus documentation and tests to validate cascading behavior and runtime provisioning outcomes.

Changes:

• Introduces transport-level AutoProvision(bool) with a topology-level default and per-resource nullable overrides (bool?).
• Updates provisioning/describe logic to respect the cascade (resource override → transport default).
• Adds docs and both unit + integration tests covering default/explicit/disabled and mixed provisioning scenarios.
