Cobra allows for aliases to be defined for a command, but only allows these
to be defined at the same level (for example, `docker image ls` as alias for
`docker image list`). Our CLI has some commands that are available both as a
top-level shorthand as well as `docker <object> <verb>` subcommands. For example,
`docker ps` is a shorthand for `docker container ps` / `docker container ls`.
This patch introduces a custom "aliases" annotation that can be used to print
all available aliases for a command. While this requires these aliases to be
defined manually, in practice the list of aliases rarely changes, so maintenance
should be minimal.
As a convention, we could consider the first command in this list to be the
canonical command, so that we can use this information to add redirects in
our documentation in future.

The `DEBIAN_FRONTEND` environment variable is used to control the interface by which debconf questions are presented to the user (see [`man 7 debconf`][1]). In `DEBIAN_FRONTEND=noninteractive apt-get update && apt-get install -y`, the `DEBIAN_FRONTEND` environment variable is only set for the `apt-get update` command which does not ask debconf questions, and will not affect the `apt-get install` command where these questions are actually asked. It should be the other way around.

The code is similar to that used by the volume rm subcommand, however,
one difference I noticed was VolumeRemove takes the force flag/option
was a parameter. This isn't the case for NetworkRemove.
To get NetworkRemove to take a similar parameter, this would require
modifying the Docker daemon. For now this isn't a route I wish to take
when the code can be arrange to mimic the same behavior.

The `~/.dockercfg` file was replaced by `~/.docker/config.json` in 2015
(github.com/docker/docker/commit/18c9b6c6455f116ae59cde8544413b3d7d294a5e),
but the CLI still falls back to checking if this file exists if no current
(`~/.docker/config.json`) file was found.
Given that no version of the CLI since Docker v1.7.0 has created this file,
and if such a file exists, it means someone hasn't re-authenticated for
5 years, it's probably safe to remove this fallback.

Remove "Docker" from registry, as the registry specification is no
longer docker-specific, but part of the OCI distribution spec.
Also removed "Register" from one of the docs pages, as the login
command hasn't supported creating a new acccount on Docker Hub for
a long time.
I'm wondering if we should be more explicit about what log in / out
does (effectively; authenticate, and on success store the credentials
or token, and on log out; remove credentials/token).

- moves those flags from the `docker create` to the `docker run` page
- does some minor rephrasing and touch-ups.

I didn't see where in the page that `--privileged` mode adds all capabilities.
I think this page once did contain that information. I got it from a Stack Overflow answer that seems to have copied from an earlier version of this same document.
> Full container capabilities (--privileged)
>
> The --privileged flag gives all capabilities to the container, and it also lifts all the limitations enforced by the device cgroup controller. In other words, the container can then do almost everything that the host can do. This flag exists to allow special use-cases, like running Docker within Docker.

This feature allowed using an encrypted private key with a supplied password,
but did not provide additional security as the encryption is known to be broken,
and the key is sitting next to the password in the filesystem. Users are recommended
to decrypt the private key, and store it un-encrypted to continue using it.

The DefaultStopSignal const has been deprecated, because the daemon already
handles a default value. The current code did not actually send the default
value unless the flag was set, which also made the flag description incorrect,
because in that case, the _daemon's_ default would be used, which could
potentially be different as was specified here.
This patch removes the default value from the flag, leaving it to the daemon
to set a default.

- make sure the target directory is created if missing
- add support for custom ID's in headings through `<a>` tags (e.g.
`<a name=heading2></a>`). This allows use of custom anchors that
work both on GitHub (GFM doesn't support extended MarkDown), and
in Jekyll (which does).
- add code to cleanup markdown for use in our docs:
- remove absolute URLs to https://docs.docker.com
- remove tabs in MarkDown, and convert them to 4 spaces. This
prevents the YAML conversion from switching between "short"
and "long" syntax. Tabs in code examples also don't always
work well, so using spaces doesn't hurt for that.
- refactor some code for readability, and to be less "hacky" (still
lots to be improved though)
