RFR(M): 8132718: Add tests which check that when humongous classloader object becomes unreachable it and all classes that were loaded in it should be collected

[Dmitry Fazunenko]

Hi Kirill,

Thanks for addressing my previous comments. The new version looks good.
I just noticed a couple of minor improvements which could be done to the 
test:

1) rename: ClassGenerator --> ClassLoaderGenerator

2) move logic from the on class loader generation from the main() method 
to a new one (just to make API look nicer):

class ClassLoaderGenerator () {
     public static void main(String[] args) throws IOException {
         // check args
         generateClassLoader(params);
     }
     public static void generateClassLoader(params) throws IOException {
         // logic on generation
}
}

Thanks,
Dima
