format (GoDoc) comments with Go 1.19 to prepare for go updates
Older versions of Go do not format these comments, so we can already
reformat them ahead of time to prevent gofmt linting failing once
we update to Go 1.19 or up.

Result of:

    gofmt -s -w $(find . -type f -name '*.go' | grep -v "/vendor/")

With some manual adjusting.

Sebastiaan van Stijn 80b1285fec cli: use custom annotation for aliases
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.

Before this patch:

    docker images --help

    Usage:  docker images [OPTIONS] [REPOSITORY[:TAG]]

    List images

    Options:
      -a, --all             Show all images (default hides intermediate images)
      ...

With this patch:

    docker images --help

    Usage:  docker images [OPTIONS] [REPOSITORY[:TAG]]

    List images

    Aliases:
      docker image ls, docker image list, docker images

    Options:
      -a, --all             Show all images (default hides intermediate images)
      ...

formatter package heavy refactoring
- 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.

Kir Kolyshkin 6f8070deb2 Switch from x/net/context to context
Since go 1.7, "context" is a standard package. Since go 1.9,
x/net/context merely provides some types aliased to those in
the standard context package.

The changes were performed by the following script:

for f in $(git ls-files \*.go | grep -v ^vendor/); do
	sed -i 's|golang.org/x/net/context|context|' $f
	goimports -w $f
	for i in 1 2; do
		awk '/^$/ {e=1; next;}
			/\t"context"$/ {e=0;}
			{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
				mv $f.new $f
		goimports -w $f
	done
done

[v2: do awk/goimports fixup twice]

With this patch applied, the default output is:
