Return information about which int tests failed in the summary

**What this PR does / why we need it**:
Currently if integration tests fail they will print the name of the failing tests as it goes, but the summary only tells that it failed. You need to know what to look for to be able to find all these occurrences. This PR provides a summary next to the failure information, eg:
```
FAILED TESTS: run_cluster_management_tests, run_plugins_tests, 
```
Which should greatly simplify developers integration debugging. 

**Release note**:
```release-note
NONE
```
