This updates the "docker pull" documentation and

Following #19995 and #17409 this PR enables skipping userns re-mapping
when creating a container (or when executing a command). Thus, enabling
privileged containers running side by side with userns remapped
containers.
The feature is enabled by specifying ```--userns:host```, which will not
remapped the user if userns are applied. If this flag is not specified,
the existing behavior (which blocks specific privileged operation)
remains.

Prior to this change, the "docker network inspect" contains only the
endpoints that have active local container. This excludes all the remote
and stale endpoints. By including all the endpoints, it makes debugging
much simpler and also allows the user to cleanup any stale endpoints
using "docker network disconnect -f {network} {endpoint-name}".

Once thin pool gets full, bad things can happen. Especially in case of xfs
it is possible that xfs keeps on retrying IO infinitely (for certain kind
of IO) and container hangs.
One way to mitigate the problem is that once thin pool is about to get full,
start failing some of the docker operations like pulling new images or
creation of new containers. That way user will get warning ahead of time
and can try to rectify it by creating more free space in thin pool. This
can be done either by deleting existing images/containers or by adding more
free space to thin pool.
This patch adds a new option dm.min_free_space to devicemapper graph
driver. Say one specifies dm.min_free_space=10%. This means atleast
10% of data and metadata blocks should be free in pool before new device
creation is allowed, otherwise operation will fail.
By default min_free_space is 10%. User can change it by specifying
dm.min_free_space=X% on command line. A value of 0% will disable the
check.

Allows users to submit options similar to the `mount` command when
creating a volume with the `local` volume driver.
For example:
```go
$ docker volume create -d local --opt type=nfs --opt device=myNfsServer:/data --opt o=noatime,nosuid
```

Also clarify that these steps must be done *before* enabling
userns-remap and starting the daemon.

This change implements communication with an external credentials store,
ala git-credential-helper. The client falls back the plain text store,
what we're currently using, if there is no remote store configured.
It shells out to helper program when a credential store is
configured. Those programs can be implemented with any language as long as they
follow the convention to pass arguments and information.
There is an implementation for the OS X keychain in https://github.com/calavera/docker-credential-helpers.
That package also provides basic structure to create other helpers.

There are five options 'debug' 'labels' 'cluster-store' 'cluster-store-opts'
and 'cluster-advertise' that can be reconfigured, configure any of these
options should not affect other options which may have configured in flags.
But this is not true, for example, I start a daemon with -D to enable the
debugging, and after a while, I want reconfigure the 'label', so I add a file
'/etc/docker/daemon.json' with content '"labels":["test"]' and send SIGHUP to daemon
to reconfigure the daemon, it work, but the debugging of the daemon is also diabled.
I don't think this is a expeted behaviour.
This patch also have some minor refactor of reconfiguration of cluster-advertiser.
Enable user to reconfigure cluster-advertiser without cluster-store in config file
since cluster-store could also be already set in flag, and we only want to reconfigure
the cluster-advertiser.

This makes it so when calling `docker run --rm`, or `docker rm -v`, only
volumes specified without a name, e.g. `docker run -v /foo` instead of
`docker run -v awesome:/foo` are removed.
Note that all volumes are named, some are named by the user, some get a
generated name. This is specifically about how the volume was specified
on `run`, assuming that if the user specified it with a name they expect
it to persist after the container is cleaned up.
