title: Zookeeper CLI - wildcard support
body: <p>Looks like zookeeper CLI (zkCli.sh) does not support wildcard - I have not looked at the zookeeper code to figure out whether it is not possible design wise or whether I am missing something silly here. </p>
  
  <p>What is the best way then to recursively delete nodes starting with a string. I would want to do something like:</p>
  
  <pre><code>./zkCli.sh rmr abc*
  </code></pre>
  
  <p>to delete all nodes that begin with abc. Is there any simpler way out other than using Java/Python or similar clients? Or in other words, is this achievable through only ZK CLI?</p>
