data should contain timestamp of actual failure of a tests function

if the test fails/is flaky we seem to keep timestamp of end of integration (which does not make sense, is redundant, we can obtain it from workitem/integration parameter). The actual value would be in storing timestamp of when the test actually failed - because then we can cross-connect it with inframetrics data about the VM parameters or even compute host parameters
