f188b9f623 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.

bce49dff0d Add freezer stats
This one is a problem because the most useful stat is a string and not a
