SPI element related to Instance are missing info about their qualifier

Following elements are related to Instance interface:

• CDI class implements Instance
• SeContainer extends Instance
• BeanManager.createInstance() returns and Instance object

If these Instance usage are all Instance<Object> there's no information regarding their qualifier.

We should state in Javadoc and spec that these Instance behaves like an injected instance with @Inject @Any Instance<Object> to allow access to all beans instance in the container.
