Rabbitmq vhost and user support

[lmiccini]

Add new notificationsBus interface to hold cluster, user and vhost names for optional usage.
The controller adds these values to the TransportURL create request when present.

Additionally, we migrate RabbitMQ cluster name to RabbitMq config struct
using DefaultRabbitMqConfig from infra-operator to automatically
populate the new Cluster field from legacy RabbitMqClusterName.

Example usage:

  spec:
    notificationsBus:
      cluster: rabbitmq
      user: custom-user
      vhost: custom-vhost
