Rust containerd shim v2 for runh container

This shim is a fork of io.containerd.runc.v2-rs and adapted for runh. By default containerd relies on runtime shim to launch containers.

Usage

To build binary, run:

cargo build --release

Copy binary to the containerd shim dir, e.g. /usr/bin/

In order to use it from containerd, use:

sudo ctr run --runtime "io.containerd.runh.v2" --rm -t ghcr.io/hermit-os/rusty_demo:latest demo
```
