Doing a Exponential moving average per nr_running++/-- does not guarantee a fixed sample rate which induces errors if there are lots of threads being enqueued/dequeued from the rq (Linpack mt). Instead of keeping track of the avg, the scheduler now keeps track of the integral of nr_running and allows the readers to perform filtering on top. Implemented a proper exponential moving average for the runnables governor and a straight 100ms average for the balanced governor. Tweaked the thresholds for the runnables governor to minimize latency. Also, decreased sample_rate for the runnables governor to the absolute minimum of 10msecs.
