1. Support Rootless Docker …

   Requirements:
   - Install rootless Docker 20.10 or later, see https://rootlesscontaine.rs/getting-started/docker/
   - Enable cgroup v2 delegation, see https://rootlesscontaine.rs/getting-started/common/cgroup2/
   
   Usage: `minikube start --driver=docker --container-runtime=containerd`.
   The `--container-runtime` flag needs to be set to "containerd".
   CRI-O can be also supported later.
   
   Closes issue 10836 ("add support for rootless Docker").
   
   Support for rootless Podman (issue 8719) is not covered in this commit.

   Code reading guide:
   - `deploy/kicbase/Dockerfile`: updated to install fuse-overlayfs and containerd-fuse-overlayfs, which is used
     instead of `overlayfs` snapshotter
   
   - `deploy/kicbase/entrypoint`: updated to verify cgroup v2 delegation.
     Mostly from https://github.com/kubernetes-sigs/kind/blob/8a83ee46b28a80ccd47a85e24294b3e149361947/images/base/files/usr/local/bin/entrypoint
   
   - `cmd/minikube/cmd/start_flags.go`: updated to set `KubeletInUserNamespace` feature gate when rootless
   
   - `pkg/drivers/kic/oci`: updated to use port forwarding, because rootless container IPs are not reachable from the host
   
   - `pkg/minikube/cruntime`: updated to generate `/etc/containerd/config.toml` with rootless support.
