`create-control-group` group

## Description

`create-control-group` is a utility that creates the process control group group with mkdir 3.

On platforms where `/proc/self/cgroup` does not exist, this command is a no-op, for script compatibility. Otherwise, that file is searched for a control group record with a blank controller field or (failing that) with a `name=systemd` controller field.

If a record of the former type is found, version 2 control groups are assumed with the single control group hierarchy rooted at `/sys/fs/cgroup`. If a record of the latter type is found, version 1 control groups are assumed with the relevant control group hierarchy (the only one that is affected by the command) rooted at `/sys/fs/cgroup/systemd`.

The command will fail if the process cannot create the given control group and it does not already exist.
