091d694c00 tests: Make cgroup tests hierarchy-aware 
Resolve cgroup filesystem paths according to the active hierarchy and
assert systemd's expected cgroup v1 limitations. This lets the existing
manager and D-Bus tests run in both guest modes without changing library
behavior.

c49bee218f systemd: Do not check systemd version 
The systemd version is purely informational and should not be parsed, as
documented in the [1]. In practice, systemd version has different formats
on OpenShift and Ubuntu.

This commit skips the version check and allows all operations. The errors
will be thrown from dbus when performing unsupported operations on obsolete
versions of systemd.

d69517847b systemd: Add unit test cases 
The tests cover `SystemdClient` and methods from `utils` mods.

Please note that the `SystemdClient` tests do not run well in parallel, but
work well in sequence. Please run them with `--test-threads=1`.

4a68c762e1 systemd: Add support for managing cgroups through systemd 
`SystemdCgroup` takes a `parent`, which is the name of a slice, and a
`unit`, which is the name of a slice or a scope unit, and provides methods
to start, kill the unit, as well as set properties for the unit.

The mods, `cpu`, `memory`, `cpuset`, and `pids`, are designed to generate
properties quickly. It hides the difference between cgroups v1 and v2, and
does simple checks for the systemd version and arguments.
