A lot of errors in Swarming rerun for flaky tests

Project Member Reported by st...@chromium.org, Mar 17 2017 
There are 45 errors out of 100 analyses.

We should investigate the reason. If it is test timeout, then we'd get the test execution time T_SECONDS from the Swarming task of the flake report, then use min(max(T_SECONDS * NUM_OF_RERUN * 2, 60 * 60), 2*60*60) as the timeout for the Swarming rerun.

As a first step, record the currently running Swarming task, and show it on the page.

Comment 5 by lijeffrey@chromium.org, Apr 10 2017 

it seems even after reducing the # of iterations to 200 still a few analyses run into timeouts. Need to investigate further how the timeout is determined, i.e. is it per test or per task and how to adjust it
