      Description

      With HDFS-9391, DataNodes in MaintenanceModes states are shown under DataNode page in NameNode UI, but they are lacking icon visualization like the ones shown for other node states. Need to extend the icon visualization to cover Maintenance Mode.

      <script type="text/x-dust-template" id="tmpl-datanode">
      <div class="page-header"><h1>Datanode Information</h1></div>
      <div>
        <ul class="dfshealth-node-legend">
          <li class="dfshealth-node-icon dfshealth-node-alive">In service</li>
          <li class="dfshealth-node-icon dfshealth-node-down">Down</li>
          <li class="dfshealth-node-icon dfshealth-node-decommissioned">Decommissioned</li>
          <li class="dfshealth-node-icon dfshealth-node-down-decommissioned">Decommissioned &amp; dead</li>
        </ul>
      </div>
