        Description copied from interface: Command
        Run this command. Commands take a ZooKeeperServer and String-valued keyword arguments and return a map containing any information constituting the response to the command. Commands are responsible for parsing keyword arguments and performing any error handling if necessary. Errors should be reported by setting the "error" entry of the returned map with an appropriate message rather than throwing an exception.
        kwargs - keyword -> argument value mapping
        Returns:
        Map representing response to command containing at minimum: - "command" key containing the command's primary name - "error" key containing a String error message or null if no error
