Increase sample rate on system_healty.memory_mobile/desktop_mobile stories

Project Member Reported by hpayer@chromium.org, Aug 19 2016

Issue description

A higher sample rate may result in more stable results and a more accurate picture of the memory usage.

I run v8.browsing_desktop/cnn with sampling period = 1000ms, 500ms, and 300ms to check if increasing the rate helps with the noise.

The results are in the attached file: the first column corresponds to 1000ms, the second - 500ms, and the third and the first columns - 300ms both.

The noise level of v8:allocated_by_malloc:effective_size_avg, v8::effective_size_avg doesn't seem to be reduced by increasing the sample rate.

I tried also sampling period of 200ms and below but that crashes with OOM in metric runner.
