The --format=json option was added for all inspect commands, but was not implemented
for "docker info". This patch implements the missing option.
Before this patch:
docker info --format=json
json
With this patch applied:
docker info --format=json

Not a fan of aliases, but unfortunately they're sometimes needed. We import both
docker/docker/registry and docker/registry and api/types/registry, so I looked
for which one to continue using an alias, and this was the one "least" used,
and which already used this alias everywhere, except for two places.

Errors always need to go to stderr.
This also fixes a test in moby/moby's integration-cli which is checking
to see if errors connecting to the daemon are output on stderr.

The docker info output contains both "local" and "remote" (daemon-side) information.
The API endpoint to collect daemon information (`/info`) is known to be "heavy",
and (depending on what information is needed) not needed.
This patch checks if the template (`--format`) used requires information from the
daemon, and if not, omits making an API request.
This will improve performance if (for example), the current "context" is requested
from `docker info` or if only plugin information is requested.

The kernel memory limit is deprecated in Docker 20.10.0,
and its support was removed in runc v1.0.0-rc94.
So, this warning can be safely removed.

Fairly straight forward. It became necessary to wrap `Plugin.Err` with a type
which implements `encoding.MarshalText` in order to have that field rendered
properly in the `docker info -f '{{json}}'` output.
Since I changed the type somewhat I also added a unit test for `formatInfo`.

Right now the only client side info we have is whether debug is enabled, but we
expect more in the future.
We also preemptively prepare for the possibility of multiple errors when
gathering both daemon and client info.

Warnings are now generated by the daemon, and returned as
part of the /info API response.
If warnings are returned by the daemon; use those instead
of generating them locally.
