In order to prepare for the kernel cgroup rework, let's introduce a new unit type to systemd, the "slice". Slices can be arranged in a tree and are useful to partition resources freely and hierarchally by the user. Each service unit can now be assigned to one of these slices, and later on login users and machines may too. Slices translate pretty directly to the cgroup hierarchy, and the various objects can be assigned to any of the slices in the tree.
