snappy-debug: demystify and extend snapd

In this talk, I'll start by discussing apparmor, cgroup, seccomp etc and talk briefly about how these all are used to create a confinement for snapped apps. Then, I'll deep dive into the world of debugging confinement issues. I'll showcase and give a small hands-on on the snappy-debug tool and show how one can use it, in different scenarios, like in the Ubuntu Core or the classic Ubuntu distro and end the talk by showing a small example, on how one can actually extend various interfaces of snapd.
