How has this code been tested

I wasn't able to find the make recipes to run reviewable, test, or generate deep copy files, crds.

@hasheddan Can you please help us figure out why check-diff is failing? It passes for me locally but doesn't seem to pass on the CI

[RealHarshThakur]

@hasheddan It doesn't produce a diff locally and check-diff doesn't complain either

[alejandrojnm]

Look good, but the check-diff failed, any idea ??

Upstream fails with the same thing according to @RealHarshThakur , so merging.
