    Description copied from class: ZooKeeperServer
    
    Sets the state of ZooKeeper server. After changing the state, it notifies the server state change to a registered shutdown handler, if any.
    The following are the server state transitions:
  - During startup the server will be in the INITIAL state.
  - After successfully starting, the server sets the state to RUNNING.
  - The server transitions to the ERROR state if it hits an internal error. ZooKeeperServerListenerImpl notifies any critical resource error events, e.g., SyncRequestProcessor not being able to write a txn to disk.
  - During shutdown the server sets the state to SHUTDOWN, which corresponds to the server not running.

Overrides:: setState in class ZooKeeperServer
Parameters:: state - new server state.
