Allow passing custom flags to minikube

[segevfiner]

e.g. kn quickstart minikube -- --ports=8080

Should be simple to support by just passing everything after a -- to minikube start

Out of curiosity, do you just need this to reach a port or are there other configs you'd like to set on minikube too?

Not opposed to this in principle, just trying to get a sense of your needs.

I happened to try adding a port for some UDP service, but there are plenty that are useful https://minikube.sigs.k8s.io/docs/commands/start/, e.g. image-repository to use a mirror, gpus to allow gpus, and so on, there are many different flags which is why I suggested a passthrough rather than trying to wrap every single flag minikube ever or will implement.
