KUTTL: generate JUnitXML reports

- switch the type to XML (the accepted value is 'xml' lowercase,
  not uppercase);
- tune the name a bit to highlight it is a report;
- add the new reportGranularity parameter which is supported
  by kuttl 0.20.0 and will restore the pre-1.17 JUnitXML format
  (granularity by test case, instead of by step);
- remove the URL of kuttl, so that it is not tied to a specific
  release.
