There are two actions that can be taken before and after a full GC. We can do a a heap dump and we can produce a class histogram.

Both these actions now use their own GC ID and are logged and recorded as separate GCs. It is more natural that they are considered part of the full GC. Especially since they make up a significant part of the pause that the application experience.

We should move these two actions inside of the GC pause reporting.
