The default output for Cobra aliases only shows the subcommand as alias, which
is not very intuitive. This patch changes the output to print the full command
as it would be called by the user.
Note that there's still some improvements to be made; due to how aliases must be
set-up in Cobra, aliases at different "levels" are still not shown. So for example,
`docker ps --help` will not show `docker container ps` as alias, and vice-versa.
This will require additional changes, and can possibly be resolved using custom
metadata/annotations.
Before this patch:
docker container ls --help
Usage: docker container ls [OPTIONS]
List containers
Aliases:
ls, ps, list
After this patch:
docker container ls --help
Usage: docker container ls [OPTIONS]
List containers
Aliases:
docker container ls, docker container ps, docker container list

All output of the usage / --help output uses spaces, and having a tab
in the output can be somewhat cumbersome (e.g. our YAML docs generator
doesn't like them, and copy/pasing the output in iTerm produces a warning).
This patch changes the output to use two spaces instead.

The top-level `docker deploy` command (using the "Docker Application Bundle"
(`.dab`) file format was introduced as an experimental feature in Docker 1.13 /
17.03, but superseded by support for Docker Compose files.
With no development being done on this feature, and no active use of the file
format, support for the DAB file format and the top-level `docker deploy` command
(hidden by default in 19.03), is removed in this patch, in favour of `docker stack deploy`
using compose files.
