When building the Dockerfiles for development, those images are mainly used to
create a reproducible build-environment. The source code is bind-mounted into
the image at runtime; there is no need to create an image with the actual
source code, and copying the source code into the image would lead to a new
image being created for each code-change (possibly leading up to many "dangling"
images for previous code-changes).
However, when building (and using) the development images in CI, bind-mounting
is not an option, because the daemon is running remotely.
To make this work, the circle-ci script patched the Dockerfiles when CI is run;
adding a `COPY` to the respective Dockerfiles.
Patching Dockerfiles is not really a "best practice" and, even though the source
code does not and up in the image, the source would still be _sent_ to the daemon
for each build (unless BuildKit is used).
This patch updates the makefiles, circle-ci script, and Dockerfiles;
- When building the Dockerfiles locally, pipe the Dockerfile through stdin.
Doing so, prevents the build-context from being sent to the daemon. This speeds
up the build, and doesn't fill up the Docker "temp" directory with content that's
not used
- Now that no content is sent, add the COPY instructions to the Dockerfiles, and
remove the code in the circle-ci script to "live patch" the Dockerfiles.

log-opts are passed to logging-drivers as-is, so the daemon is not
aware what value-type each option takes.
For this reason, all options must be provided as a string, even if
they are used as numeric values by the logging driver.
For example, to pass the "max-file" option to the default (json-file)
logging driver, this value has to be passed as a string;
```json
{
"log-driver": "json-file",
"log-opts": {
"max-size": "10m",
"max-file": "3"
}
}
```
When passed as a _number_ (`"max-file": 3`), the daemon will invalidate
the configuration file, and fail to start;
unable to configure the Docker daemon with file /etc/docker/daemon.json: json: cannot unmarshal number into Go value of type string
This patch adds an example to the daemon.json to show these values
have to be passed as strings.

A recent change in moby/moby made tests with missing client mocks fail with panic.
This adds those missing mocks for the impacted tests.

- 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.

Avoid testing for session support in non-buildkit builder to support
servers that falsely report as `1.39` compatible

The `devicemapper` storage driver is deprecated in favor of `overlay2`, and will
be removed in a future release. Users of the `devicemapper` storage driver are
recommended to migrate to a different storage driver, such as `overlay2`, which
is now the default storage driver.
The `devicemapper` storage driver facilitates running Docker on older (3.x) kernels
that have no support for other storage drivers (such as overlay2, or AUFS).
Now that support for `overlay2` is added to all supported distros (as they are
either on kernel 4.x, or have support for multiple lowerdirs backported), there
is no reason to continue maintenance of the `devicemapper` storage driver.

gofmt/goimports changed some heuristics in 1.11 and the code is now
formatted slightly differently.
No functional change, just whitespace.
