Cgroup manager for a container will always be created.
Thus, dropping the option for LinuxContainer.cgroup_manager
is feasible and could simplify the code.

if there is no such tools.

1. Implemented a rust module for operating cgroups through systemd with the help of zbus (src/agent/rustjail/src/cgroups/systemd).
2. Add support for optional cgroup configuration through fs and systemd at agent (src/agent/rustjail/src/container.rs).
3. Described the usage and supported properties of the agent systemd cgroup (docs/design/agent-systemd-cgroup.md).

and skip mount again if the storage object is known. We need to

One of the checks done by cargo-deny is ensuring all crates have a valid
license. As the rust programs import each other, cargo.toml files
without licenses trigger the check. While I could disable this check
this would be bad practice.
This adds an Apache-2.0 license in the Cargo.toml files.
Some of these files already had a header comment saying it is an Apache
license. As the entire project itself is under an Apache-2.0 license, I
assumed all individual components would also be covered under that
license.

To make cgroup v1 and v2 works well, I use `cgroups::cgroup` in
`Container` to manager cgroup now. `CgroupManager` in rustjail has some
drawbacks. Frist, methods in Manager traits are not visiable. So we need
to modify rustjail and make them public. Second, CgrupManager.cgroup is
private too, and it can't be serialized. We can't load/save it in
status file. One solution is adding getter/setter in rustjail, then
create `cgroup` and set it when loading status. In order to keep the
modifications to a minimum in rustjail, I use `cgroups::cgroup`
directly. Now it can work on cgroup v1 or v2, since cgroup-rs do this
stuff.
