DRILL-6921: Add Clear button for /options filter This commit adds the following search enhancements: 1. Addition of a clear ('x') button in the search field 2. If a filter term has been entered in the search box, on clicking the Update or Reset-to-Default button of any option, the reloaded page will re-apply the last entered filter term in the search box. 3. If the search box is empty, on clicking the Update or Reset-to-Default button of any option, the reloaded page will automatically filter out everything except the updated/reset option to show the changed value. 4. Customization of the quick search terms. (using defaults in drill-module.conf) closes #1588
DRILL-6922: Do not set return result set option on query level if it is the same as current value 1. Rename return result option name to `exec.query.return_result_set_for_ddl`. 2. Add check if option value is the same as current value in DrillSqlWorker before setting result set option on query level. 3. Separate Session and Query options on Web UI.
