Don't restrict lxc because of apparmor

We don't have the flexibility to do extra things with lxc because it is
a black box and most fo the magic happens before we get a chance to
interact with it in dockerinit.

cli.md: More typos

I've seen one other missing space that I addressed in another PR already.
I don't know whether that is a common occurrence in the docs.

About the second diff chunk, it looks like some copy-paste mistake to me.

hello_world.md - $container_id variable case sensitivity

If you run the tutorial step-by-step, following error occurs:

```$ sudo docker logs $container_id
Usage: docker logs CONTAINER
Fetch the logs of a container
  -f, --follow=false: Follow log output```

This is obviously because bash variables are case-sensitive, so it mustn't be `CONTAINER_ID` above.
