Setup unit testing github action

[arso]

Currently for build workflow unit testing execution is disabled because some of the tests are not stable enough because of for example being highly time dependent. In maven there are some profiles defined that disable unit tests annotated (with junit categories) as Performance or TimeDependent.
This lightweight workflow should be able to prepare basic OS image to run 'mvn' test on Centos Stream 8 or/and 9. As part of the jobs would be to identify other unit tests that can occasionally fail and excluded them until they are fixed.
