* Add Linux NUMA "numastat" metrics Read the `numastat` metrics from /sys/devices/system/node/node* when reading NUMA meminfo metrics. * 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. * Fixup: More fixes * Add another scanner.Err() return * Add "_total" to counter metrics.
