please add a test where both _SYSTEM_ and _SESSION_ options are changed,
and confirm the reset is working as expected.
> Provide a reset command to reset an option to its default value

> URL: https://issues.apache.org/jira/browse/DRILL-1065
> Project: Apache Drill
> Issue Type: Improvement
> Components: Execution - Flow
> Reporter: Aman Sinha
> Assignee: Sudheesh Katkam
> Priority: Minor
> Fix For: 1.2.0
>
>
> Within a session, currently we set configuration options and it would be very
> useful to have a 'reset' command to reset the value of an option to its
> default system value:
> ALTER SESSION RESET <option name>
> If we don't want to add a new keyword for RESET, we could potentially
> overload the SET command and allow the user to set to the 'default' value.
