Both Redis and Sentinel will have the capability to now define...

@ese a couple of things I have done fix... ... 1. The issue of the alpha fields. Downgraded k8s.io/api and k8s.io/apimachinery

go get -v k8s.io/api@v0.24.4
go get k8s.io/apimachinery@v0.24.4
go mod tidy
go mod vendor

And then generated CRD file.

... 2. The minikube new version has an issue with the cni plugin so downgraded it, as well.
