Suggested add Container.OnPrebuilt event.
This event can be very useful when creating features like object pools.

This event is triggered before the Build occurs

If the first event returns a value, then this value will be treated as an object instance. Subsequent OnPrebuilt events will not be triggered.

OnExtend, OnResolving, OnResolvingAfter event will be triggered normally.

• Suggested API:

public IContainer OnPreBuilt(Func<IBindData, object, object> closure);

or

protected virtual object PreBuilt(BindData makeServiceBindData, object[] userParams);
