UnmountVolumes used to also unmount 'specialMounts' but it no longer does after
a recent refactor of volumes. This patch corrects this behavior to include
unmounting of `networkMounts` which replaces `specialMounts` (now dead code).

The v2 registry will act as a pull-through cache, and needs to be
handled differently by the client to the v1 registry mirror.
See docker/distribution#459 for details
Configuration
Only one v2 registry can be configured as a mirror. Acceptable configurations
in this chanage are: 0...n v1 mirrors or 1 v2 mirror. A mixture of v1 and v2
mirrors is considered an error.
Pull
If a v2 mirror is configured, all pulls are redirected to that mirror. The
mirror will serve the content locally or attempt a pull from the upstream mirror,
cache it locally, and then serve to the client.
Push
If an image is tagged to a mirror, it will be pushed to the mirror and be
stored locally there. Otherwise, images are pushed to the hub. This is
unchanged behavior.

Having the line break in the middle of a code span caused the line break to appear on the web site version, even though it doesn't appear in the preview.
The other two changes are just small grammar improvements.

I'm fairly consistently seeing an error in
DockerSuite.TestContainerApiRestartNotimeoutParam:
docker_api_containers_test.go:969:
c.Assert(status, check.Equals, http.StatusNoContent)
... obtained int = 500
... expected int = 204
And in the daemon logs I see:
INFO[0003] Container 8cf77c20275586b36c5095613159cf73babf92ba42ed4a2954bd55dca6b08971 failed to exit within 0 seconds of SIGTERM - using the force
ERRO[0003] Handler for POST /containers/{name:.*}/restart returned error: Cannot restart container 8cf77c20275586b36c5095613159cf73babf92ba42ed4a2954bd55dca6b08971: [2] Container does not exist: container destroyed
ERRO[0003] HTTP Error err=Cannot restart container 8cf77c20275586b36c5095613159cf73babf92ba42ed4a2954bd55dca6b08971: [2] Container does not exist: container destroyed
statusCode=500
Note the "container destroyed" error message. This is being generatd by
the libcontainer code and bubbled up in container.Kill() as a result of the
call to `container.killPossiblyDeadProcess(9)` on line 439.
See the comment in the code, but what I think is going on is that because we
don't have any timeout on the Stop() call we immediate try to force things to
stop. And by the time we get into libcontainer code the process just finished
stopping due to the initial signal, so this secondary sig-9 fails due to the
container no longer running (ie. its 'destroyed').
Since we can't look for "container destroyed" to just ignore the error, because
some other driver might have different text, I opted to just ignore the error
and keep going - with the assumption that if it couldnt send a sig-9 to the
process then it MUST be because its already dead and not something else.
To reproduce this I just run:
curl -v -X POST http://127.0.0.1:2375/v1.19/containers/8cf77c20275586b36c5095613159cf73babf92ba42ed4a2954bd55dca6b08971/restart
a few times and then it fails with the HTTP 500.
Would like to hear some other ideas on to handle this since I'm not
thrilled with the proposed solution.
