This implements cgroup.Apply() using the systemd apis.
We create a transient unit called "docker-$id.scope" that contains
the container processes. We also have a way to set unit specific
properties, currently only defining the Slice to put the
scope in.

In order to handle special configuration for different drivers we
make the Config field a map to string array. This lets
us use it for lxc, by using the "lxc" key for those, and we can
later extend it easily for other backend-specific options.

docker will run the process(es) within the container with an SELinux label and will label
all of the content within the container with mount label. Any temporary file systems
created within the container need to be mounted with the same mount label.
The user can override the process label by specifying
-Z With a string of space separated options.
-Z "user=unconfined_u role=unconfined_r type=unconfined_t level=s0"
Would cause the process label to run with unconfined_u:unconfined_r:unconfined_t:s0"
By default the processes will run execute within the container as svirt_lxc_net_t.
All of the content in the container as svirt_sandbox_file_t.
The process mcs level is based of the PID of the docker process that is creating the container.
If you run the container in --priv mode, the labeling will be disabled.

When s.FinishedAt is zero, the since time exit in docker ps doesn't display correct time.
For example
```
Exited (0) 292.471209 years ago
```
This patch fixes the since time exit to display nothing if s.FinishedAt is zero.

Right now shutdown is looping over *all* devicemapper
devices and actively deactivating them, this is pretty
slow if you have a lot of non-active containers. We
instead only deactivate the devices that are mounted.
We also do the shutdown unmount using MNT_DETACH which
forces the unmount in the global namespace, even if it
is busy because of some container having it mounted.
This means the device will be freed when that container
exits.
Also, we move the call to waitClose to deactivateDevice
because all callers of any of them call both anyway.

Enable build tags for all the graphdrivers to be excludable.
As an example:
```

$ go build -tags "exclude_graphdriver_aufs exclude_graphdriver_vfs exclude_graphdriver_devicemapper"
$ ls -l docker
