Pavel Borzenkov 0e78ed63a6 Add new collector exposing 'ksmd' stats

Kernel Samepage Merging daemon.

The collector is not enabled by default.

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.

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.
