Support test result output formats like JUnit

[mnaud991]

It would be great to be able to output test results in a standard format (e.g. JUnit). That way, it would be possible to integrate Soda Core test results into a CI/CD pipelines using Azure DevOps (with the "Publish Test Results" task).
Azure DevOps seem to expect one of the following test result formats: JUnit, NUnit, VSTest, XUnit or CTest.
