Document minikube Podman support

[sftim]

This is a Feature Request

What would you like to be added
Update the page at https://kubernetes.io/docs/tasks/tools/install-minikube/ to mention that there is a podman driver, similar to the Docker driver.

I recommend that for now the Kubernetes website recommends to readers that they avoid using the podman driver; it's an initial implementation that requires running the containers as root. This should look similar to the existing advice about --vm-driver=none.

Why is this needed
There is now a podman driver in Minikube: kubernetes/minikube#6515

@sftim : the docker driver also runs containers as root, so there is no real difference there...
So the same security warnings should apply to both "docker" and "podman" drivers, if so ?

Users should continue to run in a VM, if they are not happy with running privileged containers.

And nobody should use the "none" driver, except for special use cases. It's in the minikube docs.
https://minikube.sigs.k8s.io/docs/drivers/none/

Basically it will run kubeadm init on the host...

In the new documentation, the "docker" driver is missing from the list:

1. Hypervisors
2. None
3. ?
4. Podman

So it should be described, since the "podman" driver now refers to it ?

Minikube also supports a vm-driver=podman similar to the Docker driver.

Also the link is wrong, it goes to "Docker Desktop" (for Mac and Win)

You can download .deb packages from Docker.

@afbjorklund would you be willing to repeat your comment #19218 (comment) in a new issue?

Sure thing, there seems to be several issues here. But will try go finish v1.10 with podman first...

So far it is only in beta, and "podman" driver is likely to be experimental for quite some time yet.

Seems like there already is #15969 under way, so maybe not create any more issues ?
