Delete method for Hedwig client API that uses eager cleanup
-----------------------------------------------------------

                 Key: BOOKKEEPER-151
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-151
             Project: Bookkeeper
          Issue Type: Wish
          Components: hedwig-client, hedwig-server
         Environment: Ubuntu / Centos
            Reporter: Daniel Kim


I am using hedwig as a notification system for my webapp. However, the current 
version of hedwig does not have any api for deleting topics. Since I want to be 
able to manage the resources, I tried to "delete" a topic by removing the 
znodes associated with the topic. However, the hubs do not lose their ownership 
of their delete topics until the redistribution period (e.g., lazy cleanup). 
The hubs will behave as if they still own the topic, which has no information 
in zookeeper server(s). I am hoping to see a hedwig-client api that does eager 
delete. 

As of now, the system is unthrottled and thus can grow without bound. This 
poses a threat where my resources can run out by malicious use cases, rogue 
programmers, etc.
