    In calling this method it is expected that application code will invoke the shutdown() method.
    
    For running in a Servlet Container a redeploy will cause a shutdown, and for that case we need to make sure the shutdown hook is deregistered.
  - shutdown
```
public static void shutdown()
```
    Shutdown gracefully cleaning up any resources as required.
    This is typically invoked via JVM shutdown hook.
  - registerDatabase

public static void registerDatabase(Database server)
```
    Register an ebeanServer to be shutdown when the JVM is shutdown.
  - unregisterDatabase
```
public static void unregisterDatabase(Database server)

    This is done when the ebeanServer is shutdown manually.
