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.

Peter Fern 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.

Matthias Rampke 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.

And add some missing fixtures for default collectors, even if they're
not read by tests yet.

Matthias Rampke 37c7e5e60f Add IPVS stats collector. 
This collector exposes IPVS status from `/proc/net/ip_vs` and stats from
`/proc/net/ip_vs_stats`.

Note that it is _not_ tested with IPv6, YMMV.
