The NS metadata proxy pid cleanup process hunts for and removes PIDs executing old code by using version tags. Under certain conditions it's possible for an old PID to have expired before the cleanup action has run. This change simply wraps the `pkill` command with a test to ensure the task isn't failing. Should a PID actually be cleaned up the task will print to stdout and log using the logger command.
