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.

09e610ad37 Calculate Linux disk bytes read/written based on sector size (512B)
Logical sector size appears to be fixed at 512B for the foreseeable
future in the kernel, so for now we just hard-code it.

7c47338081 Add an end-to-end test.
This test runs a selection of collectors against the fixtures and
compares the output to a reference.

The uname and filesystem collectors are disabled because they use system
calls that cannot be fixtured easily.
