info: skip client-side warning about seccomp profile on API >= 1.42
This warning will be moved to the daemon-side, similar to how it returns
other warnings. There's work in progress to change the name of the default
profile, so we may need to backport this change to prevent existing clients
from printing an incorrect warning if they're connecting to a newer daemon.

info: print errors to stderr
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.

docker info: skip API connection if possible
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.

Before:

Ian Campbell 1c576e9043 Integrate CLI plugins into `docker info`
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`.

Ian Campbell bcb06b5f58 Rework `docker info` output to be more like `docker version`
That is, reindent the two sections by one space.

While the code was done by hand the `.golden` files had the extra space
inserted with emacs' `string-insert-rectangle` macro to (try to) avoid possible
manual errors. The docs were edited the same way.

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]

Refactor/cleanup of docker info
Some mild refactoring of the docker info command;

- Use `fmt.Fprinln()` instead of `fmt.Fprintf()` where possible
- Rename `fprintfIfNotEmpty()` to `fprintlnNonEmpty()`, and removed
  return variables, because they were not used. `fprintlnNonEmpty()`
  now uses fmt.Fprintln()` instead of `fmt.Fprintf()`, because
  formatting was not used.
- Use `fprintlnNonEmpty()` to get rid of some `if` statements
- Extract printing Swarm-related information to a `printSwarmInfo()` function
- Change `Http Proxy` and `Https Proxy` to `HTTP Proxy` / `HTTPS Proxy`
