Bug Description

An unprivileged user can take up an inordinate amount of host kernel memory by creating deeply nested cgroups.

cgmanager should have a default limit (20 seems reasonable) on the cgroup depth, overrideable on the command line.

(Obviously this is just as possible with delegated cgroupfs access and mkdir, but that's irrelevant here)
