[JENKINS-19884] Unify test failure presentation

- SurefireAggregatedReport lists all aggregated failures now (its maven counterpart MatrixTestResult does it already)
- Failure summary is available wherever applicable
[JENKINS-19884] Use +/- icon instead of >>> and <<< to show and hide test failure summary
[FIXED JENKINS-19884] Visualize more information in test failure summary

Now lists error details, stack trace, stderr and stdout provided its content is
not empty.
[JENKINS-19884] .bigtable for test result lists
