Pavel Borzenkov	c12d8ea927	Add new per NUMA node memory statistics collector ... It is sometimes useful to understand the distribution of free/occupied memory between NUMA nodes to deal with performance problems. To do so, add new meminfo_numa collector that enables exporting of per node statistics along with unit and end-to-end tests for it.
