title: How to list subdirectories in Azure blob storage
body: <p>MS has announced directory like blob storage, and I'm trying to use it like directories.
   Having save some blobs by names:</p>
  
  <pre><code>Common\Service1\Type1\Object1
  Common\Service1\Type1\Object2
  Common\Service1\Type2\Object1
  Common\Service1\Type2\Object2
  Common\Service1\Type3\Object1
  Common\Service1\Type3\Object2
  Common\Service1\Type3\Object3
  </code></pre>
  
  <p>I'd like to have possibility to enumerate subdirectories, e.g. I have blobclient referenced to <code>Common</code> container name, and I would like to get subcontainers list <code>Type1, Type2, Type3</code>. Is it possible to get list of subdirectories in some directory. Using ListBlobs returns full list of blobs within current container.</p>
