[MNG-7113] config maven to mark “running test” as ERROR when some tests are skipped

**[Jan](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=kowalski)** opened **[MNG-7113](https://issues.apache.org/jira/browse/MNG-7113?redirect=false)** and commented

As a tester/developer I would like to have a flag in maven to set final verdict of running tests to ERROR when some tests has been skipped.

Flag name proposal:

markBuildAsErrorWhenAnyTestSkipped

Example using:

mvn test -DmarkBuildAsErrorWhenAnyTestSkipped=false

```
