- Trait `CgroupManager`, this abstracts over the underlying implementation of interacting with specific version of cgroups, and gives functions to add certain process to a certain cgroup, apply resource restrictions, get statistics of a cgroups, freeze a cgroup, remove a cgroup or get list of all processes belonging to a cgroup. v1 and v2 modules both contain a version specific cgroup manager which implements this trait, and thus either can be given to functions or structs which expects a cgroup manager, depending on which cgroups the host system uses.
- Apart from the trait, this also contains functions which help with reading cgroups files, and write data to a cgroup file, which are used throughout this crate.
- A function to detect which cgroup setup (v1, v2 or hybrid) is on the host system, as well as a function to get the corresponding cgroups manager.
- Functions to detect which cgroup setup (v1, v2 or hybrid) is on the host system with/without specified mounted cgroup root path, as well as functions to get the corresponding cgroups manager w/o cgroup root path.

- functions `write_cgroup_file_str` and `write_cgroup_file` which write data to a cgroup file
- function `read_cgroup_file` which reads data from given cgroup file
- function `get_cgroup_setup` which returns setup of cgroups (v1,v2, hybrid) on the system
- function `get_cgroup_setup_with_root` which returns setup of cgroups (v1,v2, hybrid) on the system with specified cgroup root path
