CRD generator implementation that supports Jakarta and Swagger

[adriansuarez]

Description

This change adds an alternative CRD generator implementation that is based on victools/jsonschema-generator.

The victools generator allows modules to be registered to customize schema generation, and there are modules that provide support for Jakarta Validation and Swagger annotations.

These changes are being contributed into test scope as a prototype, since no effort has been made to integrate it with the existing CRD generator API. It is a totally separate implementation that is not at parity with the existing generator. The intent is that someone with more knowledge of the Fabric8 codebase can incorporate some aspects of it into the real product.
