Bump up zoonavigator version

[yabinmeng]

The current zoonavigator docker image version in the helm chart is 0.6 which is deprecated. Bump up the version to the latest version.

Just this change did not work for me, but a modified deployment for zoonavigator that had the following spec section worked:

    spec:
      containers:
        - name: pulsar-zoonavigator
          image: elkozmon/zoonavigator:1.1.1
          ports:
            - name: http
              containerPort: 8001
              protocol: TCP
          env:
            - name: HTTP_PORT
              value: '8001'
            - name: CONNECTION_PULSARZK_CONN
              value: pulsar-zookeeper-0.pulsar-zookeeper:2181
            - name: CONNECTION_PULSARZK_NAME
              value: Pulsar ZooKeeper
            - name: AUTO_CONNECT_CONNECTION_ID
              value: PULSARZK
          resources:
            requests:
              cpu: 100m
              memory: 128Mi
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
          imagePullPolicy: IfNotPresent

Note the removal of the secondary container, and the modified ENV variables.
