Fixes https://github.com/gradle/gradle/issues/20773

Context TestNg have an option to run xml suites in parallel. It's very useful feature for project with big count tests stored in xml (with other params like parallel/threads-count/parameter/etc), but we still can't set up this option via gradle. In this pr I try to add this option.
