Extract metrics from CI executions to further, and quickly, be analysed to detect anomalies (OPCT-46)

Metrics we expected on the results for each execution:

• Total counters[1] for each result by plugin: Total/Passed/Skipped/Failed[...]
• Failure ratio (counter of the operation failed/total) by plugin
• Failure ratio after applying filters (recently added 'report' command)
• Total time to create the cluster*, run the tool, destroy the cluster*
