[SPARK-15330][SQL] Implement Reset Command
#### What changes were proposed in this pull request?
Like `Set` Command in Hive, `Reset` is also supported by Hive. See the link: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Cli
Below is the related Hive JIRA: https://issues.apache.org/jira/browse/HIVE-3202
This PR is to implement such a command for resetting the SQL-related configuration to the default values. One of the use case shown in HIVE-3202 is listed below:
> For the purpose of optimization we set various configs per query. It's worthy but all those configs should be reset every time for next query.
#### How was this patch tested?
Added a test case.
