Sebastiaan van Stijn 86e0c72c59 Document that ENV vars are not automatically updated ...

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).
