define test results and reporting formats

[tomkralidis]

Each global service will have its own "orchestrator" that will be able to output test results and associated reports. The following is proposed:

• test results: use the default pytest output to dump results
• reporting: consider using the report format used by pywcmp, along with running pytest with -s (to print report to stdout). Example:

{
    "ets-report": {
        "summary": {
            "PASSED": 12,
            "FAILED": 0,
            "SKIPPED": 0
        },
        "generated-by": "pywcmp 0.8.4 (https://github.com/wmo-im/pywcmp)",
        "tests": [

            },
