feature: add a v2 crd generator based on jackson (5949)

feature: add a v2 crd generator based on jackson closes: #5948 also removes v1beta1 from the new code --- fixing formatting --- fully removing v1beta1 and ordering required --- accepting the change in the printer column type also removing another reference to CustomResource --- removing erroneous v1 changes --- removing decorator classes --- wiring up new top level options --- removing deprecated method, adding another test --- Update crd-generator/api-v2/src/main/java/io/fabric8/crdv2/generator/AbstractJsonSchema.java Co-authored-by: Bernhard Strähle <[email protected]> --- Update crd-generator/api-v2/src/main/java/io/fabric8/crdv2/generator/v1/CustomResourceHandler.java Co-authored-by: Bernhard Strähle <[email protected]> --- finishing off review changes and adding a test --- Merge branch 'main' of github.com:fabric8io/kubernetes-client into crd-generator-v7-development --- replacing the YAML_MAPPER with standard serialization --- adding back a common method for printer columns also using string instead of object or array types --- adding back dependent class names --- stripping the explicit start --- removing unnecessary override
