DRILL-143: Support CGROUPs resource management
Introduces the `DRILLBIT_CGROUP` option in defined in `drill-env.sh`
The startup script checks if the specified CGroup (ver 2) is available and
tries to apply it to the launched Drillbit JVM.
This would benefit not just Drill-on-YARN usecases, but any setup that
would like CGroups for enforcement of (cpu) resources management.
e.g when Drillbit is configured to use `drillcpu` cgroup
```
[root@maprlabs ~]#
/opt/mapr/drill/apache-drill-1.14.0-SNAPSHOT/bin/drillbit.sh restart
Stopping drillbit
..
Starting drillbit, logging to /var/log/drill/drillbit.out
WARN: Drillbit's CPU resource usage will be managed under the CGroup :
drillcpu (up to 4.00 cores allowed)
```
e.g. Non-existent CGroup `droolcpu` is used
```
[root@maprlabs ~]#
/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 droolcpu does not found. Ensure that daemon is running and
cgroup exists
```
