[BUG] Qualification ui output goes to wrong folder

[tgravescs]

Describe the bug
Running the qualification tool without any options now generates the UI, but it doesn't go into the correct output folder, it just goes into ./ :

22/06/15 10:02:09 INFO ToolTextFileWriter: Stage Exec Info output location: rapids_4_spark_qualification_output/rapids_4_spark_qualification_output_stages.csv
22/06/15 10:02:09 INFO QualificationReportGenerator: Generating UI data in ui/html/index.html

This behavior seems consistent with passing --output-directory
When the tool is executed with the following argument--output-directory output_dir, the user gets:

• output_dir/ui
• output_dir/rapids_4_spark_qualification_output

Running the qualification tool without any options, the output_folder will be by default ./. This will gives two directories:

• ./ui
• ./rapids_4_spark_qualification_output

Is the ui directory supposed to be a subdirectory of rapids_4_spark_qualification_output ?
