[FEATURE REQUEST] [epicli test] Print total number of failed tests

[to-bar]

Is your feature request related to a problem? Please describe. epicli test may produce a big number of xml files (in spec_tests sub-directory) and there is no information about total failed tests. One has to check all xml files manually, for example using grep:

grep -Por 'failures="\d+"'  /workspaces/epiphany/clusters/build/alma-test-big/spec_tests | grep -cv '"0"$'
1

Describe the solution you'd like Print aggregated test results, for example: Total tests: 64 [failures: 1, errors: 0, skipped: 0]

Describe alternatives you've considered Configure rake to create single (common) output file for all groups and hosts.

Would be nice to consider another thing related to test results:

• when running tests against the cluster that has configured components that use role mapping for filebeat under configuration/feature-mapping , but doesn't include logging component, it will generate empty spec_tests result file for filebeat
• it happens because under tests/spec/Rakefile file we have specified to run tests against all groups in inventory, but in tests/spec/spec/filebeat/filebeat_spec.rb we are skipping tests if logging component is not enabled
• empty files are read by Azure to publish test results which lead to warnings about tests for filebeat

Thanks to @przemyslavic for explanation.

If you think that it requires separate ticket, please comment.
