Replace writepid with task_profiles command for cgroup migration

writepid command usage to join a cgroup has been deprecated in favor of a more flexible approach using task_profiles. This way cgroup path is not hardcoded and cgroup changes can be easily made. Replace writepid with task_profiles command to migrate between cgroups.
