The `DOCKER_HIDE_LEGACY_COMMANDS` environment variable allows hiding legacy

A while ago, Docker split the "Domainname" field out from the "Hostname"
field for the container configuration. There was no real user-visible
change associated with this (and under the hood "Domainname" was mostly
left unused from the command-line point of view). We now add this flag
in order to match other proposed changes to allow for setting the NIS
domainname of a container.
This also includes a fix for the --hostname parsing tests (they would
not error out if only one of .Hostname and .Domainname were incorrectly
set -- which is not correct).

- make it possible to extract the formatter implementation from the
"common" code, that way, the formatter package stays small
- extract some formatter into their own packages
This is essentially moving the "formatter" implementation of each type
in their respective packages. The *main* reason to do that, is to be
able to depend on `cli/command/formatter` without depending of the
implementation detail of the formatter. As of now, depending on
`cli/command/formatter` means we depend on `docker/docker/api/types`,
`docker/licensing`, … — that should not be the case. `formatter`
should hold the common code (or helpers) to easily create formatter,
not all formatter implementations.

Unlike `docker build --secret`, `docker build --ssh` allows the build container to
use SSH keys with passphrases.
$ eval $(ssh-agent)
$ ssh-add ~/.ssh/id_rsa
(Input your passphrase here)
$ docker build --ssh default=$SSH_AUTH_SOCK ...
This feature requires the daemon with `CapExecMountSSH` build capability (moby/moby#37973) .
Currently, the official Dockerfile frontend does not provide the syntax for using the SSH forwarder.
However, the experimental `RUN --mount=type=ssh` syntax can be enabled by using
the Dockerfile frontend image built with the `BUILDTAGS="dfrunmount dfssh"`, via the `# syntax =` "shebang".
The Dockerfile for the Dockerfile frontend is available at github.com/moby/buildkit/frontend/dockerfile/cmd/dockerfile-frontend)
The pre-built image is also available as `tonistiigi/dockerfile:ssh20181002` .
An example Dockerfile with `RUN --mount=type=ssh`:
# syntax = tonistiigi/dockerfile:ssh20181002
FROM alpine
RUN apk add --no-cache openssh-client
RUN mkdir -p -m 0700 ~/.ssh && ssh-keyscan gitlab.com >> ~/.ssh/known_hosts
RUN --mount=type=ssh ssh git@gitlab.com | tee /hello
# "Welcome to GitLab, @GITLAB_USERNAME_ASSOCIATED_WITH_SSHKEY" should be printed here

Deploying a stack with `$version` set would ignore the `$version`

Also, fix some CLI command confusions:
1. If the --external-ca flag is provided, require a --ca-cert flag as well, otherwise
the external CA is set but the CA certificate is actually rotated to an internal
cert
2. If a --ca-cert flag is provided, require a --ca-key or --external-ca flag be
provided as well, otherwise either the server will say that the request is
invalid, or if there was previously an external CA corresponding to the cert, it
will succeed. While that works, it's better to require the user to explicitly
set all the parameters of the new desired root CA.
This also changes the `swarm update` function to set the external CA's CACert field,
