  Now possible to attach prometheus-exporter to collect metrics as follows:

---
apiVersion: "streaming.nats.io/v1alpha1"
kind: "NatsStreamingCluster"
metadata:
  name: "example-stan"
spec:
  # Number of nodes in the cluster
  size: 3

  # NATS Streaming Server image to use, by default
  # the operator will use a stable version
  # 
  image: "nats-streaming:0.12.2"

  # Service to which NATS Streaming Cluster nodes will connect.
  # 
  natsSvc: "example-nats"

  config:
    debug: true
    trace: true
    raftLogging: true

  template:
    metadata:
      annotations:
        prometheus.io/scrape: "true"
        prometheus.io/port: "7777"
    spec:
      containers:

      # Need to list the first container for the server, the operator
      # will fill in the rest of the parameters.
      - name: "stan"

      # Define the sidecar container and the paths that should be polled.
      - name: "metrics"
