Avoid discarding precision of metering data

Fixes bug 1241467

Narrow-casting statistical aggregates to int before inserting
into the resource usage line charts had the effect of unnaturally
smoothening the trend. This was especially apparent for meters
defined over a narrow range (such as cpu_util ranging from 0.0%
to 100.0%).

We now maintain floating point precision for these data.
