2013-07-01core: move ControlGroup and Slice properties out of the dbus "Unit" interfaceLennart Poettering
Slice/ControlGroup only really makes sense for unit types which actually have cgroups attached to them, hence move them out of the generic Unit interface and into the specific unit type interfaces. These fields will continue to be part of Unit though, simply because things are a log easier that way. However, regardless how this looks internally we should keep things clean and independent of the specific implementation of the inside.

2013-06-27dbus: add infrastructure for changing multiple properties at once on units ↵Lennart Poettering
and hook some cgroup attributes up to it This introduces two bus calls to make runtime changes to selected bus properties, optionally with persistence. This currently hooks this up only for three cgroup atributes, but this brings the infrastructure to add more changable attributes. This allows setting multiple attributes at once, and takes an array rather than a dictionary of properties, in order to implement simple resetting of lists using the same approach as when they are sourced from unit files. This means, that list properties are appended to by this call, unless they are first reset via assigning the empty list.
2013-06-27core: general cgroup reworkLennart Poettering
Replace the very generic cgroup hookup with a much simpler one. With this change only the high-level cgroup settings remain, the ability to set arbitrary cgroup attributes is removed, so is support for adding units to arbitrary cgroup controllers or setting arbitrary paths for them (especially paths that are different for the various controllers). This also introduces a new -.slice root slice, that is the parent of system.slice and friends. This enables easy admin configuration of root-level cgrouo properties. This replaces DeviceDeny= by DevicePolicy=, and implicitly adds in /dev/null, /dev/zero and friends if DeviceAllow= is used (unless this is turned off by DevicePolicy=).
2013-06-17core: add new .slice unit type for partitioning systemsLennart Poettering
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.
