CRDGenerator v2: Gradle Plugin

[baloo42]

Description

Because the CRD-Generator annotation processor is now deprecated, we need a replacement.
(see #5942)

A CRD-Generator Gradle plugin could search for a top-level annotation (or interface) and generate the CRDs using the CRD-Generator v2 API.

Additional context

• Jandex could be used to find and index the relevant annotations/classes.

• The following options should be supported:

  • Enable / disable parallel generation (enabled by default)
  • CRD versions (v1)
  • outputPath
  • header in output files
  • Enable debug output

• The also planned new Gradle plugin should have feature parity with the CRD-Generator maven plugin (CRDGenerator v2: Maven Plugin #5944) should support the same options.

• The docs need updating, especially the Quickstart section which should focus strictly on the Gradle and Maven Plugins (refactor(crd-generator): deprecation of CRD Generator v1 #6674 (comment))

As suggested by @manusa we can just start with a clone of https://github.com/fabric8io/kubernetes-client/tree/main/java-generator/gradle-plugin
