Activate annotation processors again for panache

[Postremus]

We depend on the jpamodelgen annotation processor in the panache modules, to create the Meta Model for e.g. the PanacheEntity class.

Would you review this PR, please?
According to git blame, you added the proc:none initially.

FTR, proc:none was added in this commit: a28d76b (1.5.0.CR1).

We don't want PanacheAnnotationProcessor (a28d76b#diff-3b62cdfb1058fa132560380d194f6b00371f9426fdc7f4bf759a2ccb36c7febaR28) to be run, can you change this to just run the hibernate one?

[Postremus]

@stuartwdouglas done

[stuartwdouglas]

Can we also add a test for this to make sure that we don't run into this in future? Otherwise looks good.

[Postremus]

@stuartwdouglas Added a simple test to hibernate-panache and hibernate-reactive-panache, which just checks if the metamodel was generated.

Thanks @Postremus!

@ninaHerpertz Simply adding the hibernate-jpamodelgen annotation processor should work in your case. See https://quarkus.io/guides/hibernate-orm-panache#defining-entities-in-external-projects-or-jars

You need to do this anyway, even for PanacheEntity.
Quarkus uses jpamodelgen for meta-model generation inside the quarkus-hibernate-orm-panache module. Any other modules containing entities need to define this annotation processor seperatly.
