docs: remove outdated reference to updating /etc/hosts

Browse source

/etc/hosts for service discovery, but uses an
embedded DNS server. This patch removes a reference
to the old (pre 1.10) behavior.

with other containers, then the container's `/etc/hosts` file is updated
with the linked container's name.
If the container is connected to user-defined network, the container's
`/etc/hosts` file is updated with names of all other containers in that
user-defined network.

may be situations when processes inside the container can end up reading an
empty or incomplete `/etc/hosts` file. In most cases, retrying the read again
