title: IReliableReadWriteDocumentClient is missing PartitionResolver in Document DB
body: <p>When returned DocumentClient <code>AsReliable</code>, it doesn't have PartitionResolvers. Any way to get around this?</p>
  
  <pre><code>var documentClient = new DocumentClient(new Uri(endPointUrl), authorizationKey);
  
  var documentRetryStrategy = new DocumentDbRetryStrategy(RetryStrategy.DefaultExponential) { FastFirstRetry = true };
  return documentClient.AsReliable(documentRetryStrategy);
  </code></pre>
