Added

• Added extraRoutes field to extend a cluster mesh with other NATS clusters (#130)

apiVersion: "nats.io/v1alpha2"
kind: "NatsCluster"
metadata:
  name: "nats-dev-v2"
spec:
  size: 3
  version: "1.4.1"

  extraRoutes:
    # Explicit route endpoint
    - route: "nats://example.com:6222"

    # Discover implicit routes from nats-dev-v1 cluster
    - cluster: "nats-dev-v1"

• Added support for annotations (#111)

apiVersion: "nats.io/v1alpha2"
kind: "NatsCluster"
metadata:
  name: "nats-dev-v1"
spec:
  pod:
    # Disable istio on nats pods
    annotations:
      sidecar.istio.io/inject: "false" 

• Added support to allow a single operator to manage clusters in the whole cluster.
  Currently the operator has to be deployed on the nats-io namespace to work cluster wide,
  and it can be enabled by setting the flag --feature-gates=ClusterScoped=true when starting the operator (#118)
