title: Add retry mechanism for bolt on Apache Storm
body: <p>I have a bolt (dispatcher) in my storm topology which open http request connection.</p>
  
  <p>I want to add retry mechanism in-case of failure (connection time out, fail status, etc..). 
  The retry should occur only in the dispatcher-bolt and not to start over the whole topology.</p>
  
  <p>usually what I would do is to add a queue which would be responsible for the retry and exception handling (for example after 3 time automatically dispatch the message to an error queue..)</p>
  
  <p>Is it OK to do such thing inside a bolt? anyone has any experience with that and could suggest which library I could use?</p>
