This commit adds an example for container migration in Kubernetes
cluster. This example consists of several components:
- `http-server`: an HTTP server that responds with the hostname
and IP address of the container it is currently running into.
- `local-registry`: a set of scripts for setting up a local container
registry that can be used to distribute container checkpoints
across cluster nodes.
- `build-image`: a script building an OCI container image from
checkpoint tar archive
- `kubectl-plugin`: a plugin introducing a `checkpoint` command
to kubectl
- `manifests`: yaml files for deploying the HTTP server example and
kube-router
- `cni`: a cni configuration for kube-router
