`[MAJOR]` New approach to running SteamOS using systemd-in-docker

[wanjohiryan]

The idea here is to run Dind mode.

Rough idea:

1. Have a base docker image that will house every other container, it should run like a VM as we will need the /dev/uinput kernel module to create virtual input nodes
2. The base image should be able to access /sys/fs/cgroup/devices/kubepods/ (for kubernetes) and /sys/fs/cgroup/devices/docker/ (for vanilla docker) on every run.
3. Have SteamOS or any other game container running inside this base container.
4. I am still undecided on whether to run ffmpeg and Xserver and pulseaudio in their own docker containers. I will update this when am done.

TODO:

• [x] Add ffmpeg
• [x] Add the go binary to the docker container
• [x] Import certs into the container
• [ ] Test on a remote server
