Manager cgroup operation interface for different sub-systems. if v1 and v2 versioned cgroup system will perform different actions, it should be organized in manager; otherwise, implement in general util file instead.

func GetManager

func GetManager() Manager

GetManager returns a cgroup instance for both v1/v2 version
