[Findit] Update WfAnalysis to save flaky test information.

Before we only update WfAnalysis.result to save flaky tests found by try job but not swarming reruns.

This change will also update WfAnalysis.result to save first time flaky tests found by swarming reruns.

Also add a new field flaky_tests in WfAnalysis to explicitely save such information, and also in case there is no WfAnalysis.result when heuristic analysis aborts unexpectedly.
