    @Ben-Zvi / @paul-rogers 
    I discovered that the path `/cgroup` is unique only to my installation of the package
on CentOS. The standard path is `/sys/fs/cgroup`.
    So, I've made changes that allow for users to specify the CGroups location. Without this,
the latest commit complains as expected:
    ```
    [root@kk127 ~]#  /opt/mapr/drill/apache-drill-1.14.0-SNAPSHOT/bin/drillbit.sh restart
    Stopping drillbit
    ..
    Starting drillbit, logging to /var/log/drill/drillbit.out
    ERROR: CGroup drillcpu not found. Ensure that daemon is running, SYS_CGROUP_DIR is correctly
set (currently, /sys/fs/cgroup ), and that the CGroup exists
    ```
    The `drill-env.sh` also specifies that the enforcement is only for CPU. I'll put this
in the documentation of the feature as well.

> For the purpose of playing nice on clusters that don't have YARN, we should write up
configuration and scripts to allows users to run Drill next to existing workloads without
sharing resources.
