      .Enablement of Nova notifications in RHOSO

      This update adds support for configuring a dedicated notifications message bus in the `nova-operator`. By setting the `notificationsBusInstance` in the Nova custom resource (CR), operators can specify an external RabbitMQ for emitting versioned and unversioned notifications.

      The `[notification]` and `[oslo_messaging_notifications]` sections are rendered in `nova.conf`.

      When `novaEnabledNotification` is set and a `transport_url` is provided via an OpenShift secret, `nova-compute` emits structured notifications to external systems, improving integration and observability in RHOSO environments.

      To enable Nova notifications in RHOSO, you update the `OpenStackControlPlane` CR to add a new RabbitMQ instance and reference it in the Nova CR by using `notificationsBusInstance`. The `nova-operator` configures control plane services automatically.

      For data plane updates, redeploy the data plane nodes.

      < Goal based statement, with context - remove these notes before saving -->

      • As a User, I Want to know how to configure notifications bus via OSCP spec services template for Nova, so that the Telemetry Operator or external scripts/consumers could consume it

      Acceptance Criteria:

      <-- Notes for defining Acceptance Criteria  - remove these notes before saving -->

      A list of verification conditions, successful functional tests, or expected outcomes in order to declare this story/task successfully completed.

      • Verify that after following the documented steps, Nova publishes notifications via configured transport_url, by using AMQP credentials configured in the related transport url secret by RabbitMQ cluster operator.
