RFR(S, TESTONLY): JDK-8148315 Create a basic reproducer for JDI issues

[Dmitry Samersoff]

Everybody,

Please review an RFE

http://cr.openjdk.java.net/~dsamersoff/JDK-8148315/webrev.01/

This fix adds basic LingeredApp based reproducer (and template for more
sophisticated reproducers) to debug JDI and underlying JVMTI issues.
