Add verbosity to controller-gen

[grzesuav]

Recently I stumble upon a situation when running controller gen had no effect

controller-gen crd:headerFile="hack/boilerplate.go.txt",year=2024 paths="./pkg/api/..." output:dir="."

for the crd gen, but worked fine for object gen

controller-gen object:headerFile="hack/boilerplate.go.txt",year=2024 paths="./pkg/api/..."

(it produced output)

When I wanted to dig into it, I realized there is no way to enable verbose output in controller-gen, which would help to debug it.

Would be nice to have this feature

Initial idea would be to add logr.Logger interface, configure some initial logger (like zap) and add a flag to enable verbose logging - of course as writing to sdtout it would conflict with output:stdout but it is expected
