Unlike the entries in `/etc/hosts`, environment-variables for linked
containers are not automatically updated if the linked container is
restarted.
This adds a note to the documentation in;
https://docs.docker.com/userguide/dockerlinks/#environment-variables
and
https://docs.docker.com/reference/run/#env-environment-variables
To make users aware that this is the case and recommends them to use
the `/etc/hosts` entries in stead.
I added this change because users were expecting environment variables
to be updated automatically as well (https://github.com/docker/docker/issues/10164).
