The scratch image used to be a regular image, but as of
commit 8936789919 it is a
special case, and cannot be used with 'docker pull.'
Update this doc to reflect the new behavior and clear up
confusion surrounding this image.

Having the line break in the middle of a code span caused the line break to appear on the web site version, even though it doesn't appear in the preview.
The other two changes are just small grammar improvements.

The `--userland-proxy` daemon flag makes it possible to rely on hairpin
NAT and additional iptables routes instead of userland proxy for port
publishing and inter-container communication.
Usage of the userland proxy remains the default as hairpin NAT is
unsupported by older kernels.

The existing page is focused on listing a set of requirements for
proposing a new repository. This information has become outdated and is
duplicated in the `docker-library/official-images` and
`docker-library/docs` GitHub repositories. This PR rewrites the
Official Repositories page to describe what they actually are, and
defers to GitHub/IRC for the subset of users that are interested in
contributing. I also removed the requirement to contact
partners@docker.com and made it optional to reduce the barrier to entry.

We now advise people to configure docker group and
add to sudo. Mac shouldn't use sudo. Removed sudo
from command examples. Left in installation to be removed
in installation doc sweep -- removing requires finer
grain control.

This patch adds detail on how the host's `/etc/resolv.conf` file is
filtered when creating the copy for the container.

Read `/proc/sys/net/ipv4/ip_local_port_range` kernel parameter to obtain
ephemeral port range that now sets the boundaries of port allocator
which finds free host ports for those exported by containers.

The overlay filesystem does not support inotify at this time. The
resolv.conf updater test was passing on overlay-based Jenkins because of
a fluke--because it was DIND, /etc/resolv.conf on the "host" was really
a bind-mounted resolv.conf from the outer container, which means a watch
directly on that file worked as it was not overlay backed. The new test
(from #10703) unmounts the bind-mounted copy to test create and modify
code-paths, which caused us to hit the issue.
This PR also adds a note to the docs about the lack of auto-update when
using the overlay storage driver.
See https://lkml.org/lkml/2012/2/28/223 for more info on inotify and
overlay.
