crosperf: Add top_interval argument to experiment
Added the following optional argument in the global settings:
"top_interval" - Run top command in the background of a benchmark with
interval of sampling specified in seconds (float type).
With zero value don't run top (default value).
Top output is stored in <resultsdir>/top.log.
BUG=chromium:966514
TEST=unittests and HW tests on eve, kevin64, scarlet passed.
