* Update end-to-end test output.
* Add `numastat` metrics as counters.
* Add tests for error conditions.
* Refactor meminfo numa metrics struct
* Refactor meminfoKey into a simple struct of metric data.
  This makes it easier to pass slices of metrics around.
* Refactor tests.
* Fixup: Add suggested fixes.

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.
