We need to add delegate yes to docker's service file so that it can
manage the cgroups of the processes that it launches without systemd
interfering with them and moving the processes after it is reloaded.
```
Delegate=
Turns on delegation of further resource control partitioning to
processes of the unit. For unprivileged services (i.e. those
using the User= setting), this allows processes to create a
subhierarchy beneath its control group path. For privileged
services and scopes, this ensures the processes will have all
control group controllers enabled.
```
This is the proper fix for issue #20152

Instead of using a process expansion to feed the right arguments to
docker to run on "mh-keystore", just moves up the next step which makes
"mh-keystore" the default target. This makes the guide a bit shorter and
easier to understand.

Because devices will be bind-mounted instead of using `mknod`, we need
to make sure the source exists and filter the list by only those whose
source is a valid path/current device entry.

Attempt layer mounts from up to 3 source repositories, possibly
falling back to a standard blob upload for cross repository pushes.
Addresses compatiblity issues with token servers which do not grant
multiple repository scopes, resulting in an authentication failure for
layer mounts, which would otherwise cause the push to terminate with an
error.

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.

In cases where the a plugin responds with both a null or empty volume
and a null or empty Err, the daemon would panic.
This is because we assumed the idiom if `err` is nil, then `v` must not
be but in reality the plugin may return whatever it wants and we want to
make sure it doesn't harm the daemon.

Add a check in `check-config.sh` to see if we are running on a RHEL7 or
CentOS7 system, which may report that CONFIG_USERNS is OK/enabled, but
user namespaces still won't work because of the experimental feature
flag added by Redhat.
This will add a warning if it is actually disabled and notes what has to
be added to the grub/boot command line to enable it.
