WIP: Only c++ ci
Bug-fix:
- Logger fixed to not log all MPI ranks, but only specified ranks
- MPI tests using MPI Logger
- Sanitized exclude paths for coverage
Changes:
- Boost needs to be at least version 1.67
- Additional Tags for CI jobs, to better mark needed features on GitLab runner
- All CI Module loading moved in central functions in ci_funcs (with version selection, without default)
- Using new GitLab runner
New:
- Separate Tests for serial and mpi tests, now collected in separate files
- Tests registered in Boost compared to tests listed in files
- formatting correction for cmake files
