ARROW-3115: [JAVA] Style checks - fix import ordering First task in enabling the build to fail on Java style checks. This enables the build to fail, but is temporarily only checking style on import order. The import order rules have been changed slightly to add a "same package" group to appear last which will be the Arrow imports for that project. Also, standard java has been moved up and special imports in between 3rd party and Arrow.
