Comment 1 for bug 1439247

So some comments regarding 1/

* I am not sure if we want to make NUMA topology (even if single cell) exposed to every instance without a way to turn it off. There may be guest OS concerns around that for the libvirt case.
* The NUMA information makes no sense at this point for other drivers, some of which may never implement it.

Based on that it seems to me that a cleaner approach is to keep the NUMA qualities of instances optional

2/ Seems like a better approach to me - as for how to keep the smallest page size information in sync - two things come to mind: either don't report the smalles size at all, or make sure that resource tracker considers it and tracks it even for non-numa instances. I slightly prefer the first option
