Re: [PR] [fix][broker] Consumer stuck when delete subscription __compaction failed [pulsar]

   @poorbarcode I fixed a checkstyle issue and a problem in using MockZooKeeper's `delay` method. After #23988, MockZooKeeper is correctly single threaded and a delay will block the execution of this code in ZKSessionWatcher:
   
   https://github.com/apache/pulsar/blob/6e8c3496647df275071190aec9d29ecbcee55e80/pulsar-metadata/src/main/java/org/apache/pulsar/metadata/impl/ZKSessionWatcher.java#L108-L115
   
   This will trigger a ConnectionLost session event. That's why a delay should be kept under 2000 ms. 
   Currently MockZooKeeper's session timeout is hard coded to 30000ms and the check interval is 1/15 of this, therefore 2000ms.
