Rabbitmq vhost and user support

[lmiccini]

Add support for a dedicated rabbitmq cluster for notifications.

Add new messagingBus and notificationsBus interfaces 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:
messagingBus:
cluster: rpc-rabbitmq
user: rpc-user
vhost: rpc-vhost
notificationsBus:
cluster: notifications-rabbitmq
user: notifications-user
vhost: notifications-vhost
