The experimental feature to run Linux containers on Windows (LCOW) was introduced
as a technical preview in Docker 17.09. While many enhancements were made after
its introduction, the feature never reached completeness, and development has
now stopped in favor of running docker natively on Linux in WSL2.
Developers that need to run Linux workloads on a Windows host are encouraged
to use Docker Desktop with WSL2 instead.

The CLI disabled experimental features by default, requiring users
to set a configuration option to enable them.
Disabling experimental features was a request from Enterprise users
that did not want experimental features to be accessible.
We are changing this policy, and now enable experimental features
by default. Experimental features may still change and/or removed,
and will be highlighted in the documentation and "usage" output.
For example, the `docker manifest inspect --help` output now shows:
EXPERIMENTAL:
docker manifest inspect is an experimental feature.
Experimental features provide early access to product functionality. These features
may change between releases without warning or can be removed entirely from a future
release. Learn more about experimental features: https://docs.docker.com/go/experimental/

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.

Some deprecations are ammended during a major (YY.MM) release, to
inform users as early as possible about deprecations. Removing the
minor version from this overview clarifies that features are
marked deprecated during which major release's lifecycle.

Analysis takes more than 10 minutes, which is quite long to
run, so change it to only run on a cron job.
Also changing the cron to run on Thursdays instead of Fridays;
no need to worry about security issues during the Weekend.

If a file contains trailing whitespace, the YAML generator uses a
compact format, which is hard to read.

When initializing the API client, the User-Agent was added to any custom
HTTPHeaders that were configured. However, because the map was not properly
dereferenced, the original map was modified, causing the User-Agent to also
be saved to config.json after `docker login` and `docker logout`:
Before this change;
$ cat ~/.docker/config.json
cat: can't open '/root/.docker/config.json': No such file or directory
$ docker login -u myusername
Password:
...
Login Succeeded
$ cat ~/.docker/config.json
{
"auths": {
"https://index.docker.io/v1/": {
"auth": "<base64 auth>"
}
},
"HttpHeaders": {
"User-Agent": "Docker-Client/19.03.12 (linux)"
}
}
$ docker logout
{
"auths": {},
"HttpHeaders": {
"User-Agent": "Docker-Client/19.03.12 (linux)"
}
}
After this change:
$ cat ~/.docker/config.json
cat: can't open '/root/.docker/config.json': No such file or directory
$ docker login -u myusername

$ cat ~/.docker/config.json

Commit 01cd748eb6 started using
Dockerfile features that are currently only supported with
buildkit enabled.
While we enabled buildkit in our Jenkinsfile, the makefile
did not do the same, causing some targets to fail if buildkit
was not enabled.
This patch updates the makefile to enable buildkit.

The Dockerfile `ENV` instruction allows values to be set using either `ENV name=value`
or `ENV name value`. The latter (`ENV name value`) form can be ambiguous, for example,
the following defines a single env-variable (`ONE`) with value `"TWO= THREE=world"`,
but may have intended to be setting three env-vars:
ENV ONE TWO= THREE=world
This format also does not allow setting multiple environment-variables in a single
`ENV` line in the Dockerfile.
Use of the `ENV name value` syntax is discouraged, and may be removed in a future
release. Users are encouraged to update their Dockerfiles to use the `ENV name=value`
syntax, for example:
ENV ONE="" TWO="" THREE="world"

The `ENV key value` form can be ambiguous, for example, the following defines
a single env-variable (`ONE`) with value `"TWO= THREE=world"`:
ENV ONE TWO= THREE=world
While we cannot deprecate/remove that syntax (as it would break existing
Dockerfiles), we should reduce exposure of the format in our examples.

These annotations use `nil` as value, which caused the flag-hiding functions
to ignore the annotations, and therefore not hiding the flags.
