Have separate sampler per heap. This will allow us to have separate sampling rates per heap (e.g. ART Allocation Tracking could be higher volume, so we want a higher interval). This also is necessary if we want to allow clients to report samples rather than allocations for their heap, because that will cause that heap to have a separate (implicit) sampler, while all the others share one.
