While dual-logging is enabled automatically, it is possible to disable
this feature, or to configure the default options. This patch adds
documentation for these options.

BuildKit allows using alternative Dockerfile syntaxes to introduce new features
without having to update Docker itself. The general recommendation is to always
specify a "syntax" directive in a Dockerfile, so that (if needed) older versions
of Docker can download the correct syntax to build the Dockerfile.
This updates our examples to include a syntax directive, to make users more familiar
with these directives, and to illustrate best-pracitces in our documentation.

The logging driver bears not relation to the output of commands such as
`docker inspect`, so this line was incorrect.
Looks like this was added as part of a bigger rewrite/refactor in
d536881651, so likely missed

Using noopener, as that addresses the security issue. "noreferer" blocks
the REFERER header, which may still be useful for some target URLs.

* Removed wrong information about container DNS
In the docs it says a container will inherit the host /etc/hosts file along with /etc/resolv.conf. While the latter part is correct, /etc/hosts will not actually be inherited, as reported https://github.com/moby/moby/issues/39311.
An additional line of text has been added to emphasize the fact that /etc/hosts are not inherited
* Removed extra hash on the run command redirect
* Update config/containers/container-networking.md

Adding `-it` on a "detached" (`-d`) container is needed
if the container's main process expects a TTY attached to keep
running.
It's not needed for a redis container, so we can remove it here

Mention that `docker update` can change the restart policy for an already running container.
Otherwise, the reader is led to believe the policy can only be set when the container is started.
It was discovered that compression in gelf logging driver
is highly inefficient in terms of CPU. IOW, lots of CPU
is used when compression is enabled.
The natural solution would be to change the default
to `none`, i.e. no compression, but that would break
some setups (in particular, using Logstash < 7.4).
The only option left is to warn the user about the
consequences of leaving the compression enabled.
