Is that precisely what's needed or would it be sufficient to know that the pid is running in a child pid namespace of the current pid namespace? If so, I think this could eventually be done by comparing the inode numbers assigned to /proc/<pid>/ns/pid to those of /proc/1/ns/pid.

There were patches for a timerslack cgroup controller but for some reason (I don't recall why) they stalled. It might be worth digging through the containers mailing list archives.
