Mock storage space checks for tests.BenjaminSchubert/fix-quota-tests

Fix #530

- Extract free space computation in a function for easier
mocking
- Mock space computation during cache quota tests
- Mock cache size during cachque quota tests
- Add two more tests when the configuration would require
to much storage space
