Define the relevant rbac / service accounts / network policies

[zadigus]

Our pods are not deployed in a secured manner. See the following documentation for more information:

• rbac
  • RBAC rules should sometimes be created in order to bind the ServiceAccount to a role that allows pods to query the K8s API; this is especially useful for RabbitMQ which needs to get the list of k8s nodes from the k8s API
• service account
• network policiy

Tasks (TO BE COMPLETED):

• [ ] rabbitmq
  • [ ] enable the plugins: "rabbitmq_management rabbitmq_peer_discovery_k8s" (cf. rabbitmq devspace deployment configuration) <-- needs rbac active
  • cf. production values
  • cf. current issue if the plugin is active
  • [ ] remove the configuration section from rabbitmq devspace deployment definition
