Podman needs extra capabilities (NET_RAW and MKNOD)

[viktomas]

Hello, first, thank you to haugene and the community for this project. Saved me a lot of time.

The docker run instructions specify the --cap-add=NET_ADMIN capability so the container can create the tunnel.

With podman the following capabilities are needed:

• NET_ADMIN and MKNOD to create the tunnel
• NET_RAW because the container runs the ping command somewhere in the setup phase

so the argument for podman is --cap-add NET_ADMIN,NET_RAW,MKNOD.

I don't see many people using podman here, but if people would be interested, I can create a PR to add this info to the documentation. It was the only thing I had to spend time figuring out, rest of the project worked out-of-the-box 🎉 🙇

Feel free to add it to the documentation under tips perhaps?
Thanks
