[SPARK-12692][BUILD] Scala style: check no white space before comma a…

…nd colon

We should not put a white space before `,` and `:` so let's check it.
Because there are lots of style violations, first, I'd like to add a checker, enable and let the level `warning`.
Then, I'd like to fix the style step by step.
