This removes the metric vec that was holding onto all task id and namespace combinations forever, until containerd was restarted. This was causing a memory leak with many task. This also removes the shim cmd where the `Args` is quite large from the reaper after the shim has been started cutting down on another leak. This is the first pass through the reaper but more code is required to fix all the issues when commands are added. Signed-off-by: Michael Crosby <crosbymichael@gmail.com>
