b5b239af1d cgroups: Update systemd to match fs backend
This updates systemd.Apply to match the fs backend by:
* Always join blockio controller (for stats)
* Support CpusetCpus
* Support MemorySwap

Also, it removes the generic UnitProperties in favour of a single
option to set the slice.

bcfc527abb Separating cgroup Memory and MemoryReservation.
This will allow for these to be set independently. Keep the current Docker behavior where Memory and MemoryReservation are set to the value of Memory.

33fab479ef cgroups: Add systemd implementation of cgroups
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.

fce532280b cgroups: Splity out Apply/Cleanup to separate file/interface
This leaves only the generic cgroup helper functions in cgroups.go and
will allow easy implementations of other cgroup managers.

This also wires up the call to Cleanup the cgroup which was missing
before.

3de41b34a2 libcontainer: Initial version of cgroups support
This is a minimal version of raw cgroup support for libcontainer.
It has only enough for what docker needs, and it has no support
for systemd yet.
