Since I struggled to understand and find information about how to
troubleshoot a running linuxkit instance, I propose to add these two
FAQ entries.
The first one explains why it is possible to not see the `containerd` or
`init` outputs at boot in the console.
The second one gives a few `ctr` example to list containers, running
containers or how to open a shell in a given container.

This covers the base docs; I also did a bunch of cleanup and
remove old docs that are no longer needed.
