In Drill 1.13, you had to update the `cgroup.procs` file with the Drill
process ID (PID) each time a Drillbit restarted in order to enforce the CPU
limit for the Drillbit service. As of Drill 1.14, Drill can directly manage
the CPU resources through the Drill start-up script, `drill-env.sh`. You no
longer have to manually add the PID to the `cgroup.procs` file each time a
