   * An interface that controls the Kryo instance used by Storm for serialization. The lifecycle is:
   *
   * 1. The Kryo instance is constructed using getKryo
   * 2. Storm registers the default classes (e.g. arrays, lists, maps, etc.)
   * 3. Storm calls preRegister hook
   * 4. Storm registers all user-defined registrations through topology.kryo.register
   * 5. Storm calls postRegister hook
   * 6. Storm calls all user-defined decorators through topology.kryo.decorators
   * 7. Storm calls postDecorate hook
