There are two reasons for developing based on cgroup v1:
1. In the Internet scenario, a large number of services
are still using cgroup v1, cgroup v2 has not yet been
popularized.
2. The mechanism of cgroup pool refers to cgroup1_rename,
but for some reasons, a similar rename mechanism is not
implemented on cgroup v2, and I don't know the thoughts
behind this.
