Rerun failed tests a second time

For the continuous tests rerun failed tests a second time. This should reduce the number of failing test pipelines. In most cases of failing tests the Geant3 simulations crash due to the well known memory error. If these tests are restarted they normally work without problem. Since the feature to restart tests is only available with cmake 3.17 change the scripts of the CI pipeline to use at least this version.
