Migrate 601-spring-data-primitive-types from the Quarkus Beefy Test Suite about quarkus-test-suite

[Sgitario]

What problems with JSON libraries ?

I did not investigate it enough at first and went on with the split, but later, I dove a bit deeper and identified two "problems", or rather unadressed mistakes, both of which I have been able to resolve:

• 601 used JSON-B, whereas 602 used Jackson. I switched 601 to Jackson, but did a poor job switching annotations on entity properties which form a relationship between entities Book and Address, causing the Jackson to not serialize Book#publisherAddress, which led to failing tests. All that was needed was to use @JsonIgnore on Address#books.
• Introducing quarkus-spring-data-rest dependency into 601 caused a collision of exported endpoints from BookResource and BookRepository. The solution was to disable automatic export of the repository endpoints using @RepositoryRestResource(exported = false).

ATM, I have a working code with both modules merged together.
I can finish the two original PRs and then file a new PR containing the merger.
@rsvoboda @Sgitario WDYT?

+1 with finish off the two PRs and then refactor them into one.

I ran into problems with JSON libraries when trying to combine modules 601 and 602. For now, I proceeded with migration of the two modules separately, so I'm changing this issue to deal with 601 only. The other module is addressed in #133.
