Hi all,

could you please review this fix for ctw test?
in some configurations the test takes too much time, it also didn't have timeout, so in case of a hang, e.g. due to JDK-8189604, no one interrupted its execution.
  
the fix splits the test into several tests, one for each jigsaw module, which not only improves the tests' reliability and reportability, but also speeds up the execution via parallel execution. 2 hours timeout, which is enough for each particular module, has been added to all tests. the patch also puts ctw for java.desktop and jdk.jconsole modules in the problem list on windows.
