* Improve stat linux metric names.
cpu is no longer used.
* node_cpu -> node_cpu_seconds_total for Linux
* Improve filesystem metric names with units
* Improve units and names of linux disk stats
Remove sector metrics, the bytes metrics cover those already.
* Infiniband counters should end in _total
* Improve timex metric names, convert to more normal units.
See

for what stabil means, looks like a moving average of some form.
* Update test fixture
* For meminfo metrics that had "kB" units, add _bytes
* Interrupts counter should have _total
