cgclassify: A command line tool to classify/re-classify already running task

From: Vivek Goyal <vgoyal@redhat.com>

o cgclassify, a command line tool to put a list of pids to the right cgroup
  based on rules in /etc/cgrules.conf. It can be mainly used for
  reclassification of tasks which are already running. Can think of two
  use cases.
        - During initial bootup, after cgroups are mounted, one needs to
          move tasks (started beofore cgroups were mounted) into right
          cgroup.

        - Once can choose to reclassify the tasks if admin has changed the
          rules and thinks a group of tasks should reclassified based on
          new rules.
