cgroups-rs exposes oci-spec types in its public API (e.g.
Manager::set() takes &LinuxResources), so the version pinned here
dictates which oci-spec version every consumer must use: 0.x lines
are semver-incompatible, and a consumer on a newer oci-spec gets
"expected LinuxResources, found LinuxResources" type mismatches.
Kata Containers is moving its workspace to oci-spec 0.10.0 and
cannot call into cgroups-rs until this crate follows. The 0.8 to
0.10 changes are additive for everything cgroups-rs touches (no
code changes needed): the crate builds warning-free with the oci
feature and the unit tests pass (the only failures are the
pre-existing fs manager tests that need root to write cgroupfs).

The tests cover the methods of `conv` mod, `FsManager`, and
`SystemdManager`. Since we have to manipulate the cgroups during testing,
the tests related to this part are set to be run in sequence.

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`.

`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.

`Manager` is a trait to unify the interface of cgroups. It is designed for
OCI containers. Its `set()` takes Linux resources of the OCI spec to set
cgroups.
The `FsManager`, the concrete implementation of `Manager`, manipulates
cgroups through cgroupfs, and supports both cgroups v1 and v2.

This removes the only place the regex crate is used, which could lead to significant binary size savings in projects that don't use the regex craate.
