LockFlag (g9 Common 2.9.0 API)

```
public interface LockFlag
```
Interface specifying the methods used with optimistic lock. When GenerateLockFlag is specified in domain generator, persistent domain classes should implement the methods in this interface. However, the classes don't needs to specify the implementation of the interface. The runtime uses reflections to see if the methods is implemented, but specifying the implementation will have impact on the performance.
