Change production configuration

[nbirillo]

We use numpy and pandas modules only in the evaluation module in the tests. We can ignore the installation of them in production if we don't run evaluation tests (see open PRs #44 & #46 for issue #43, alpine requires to add an additional step for it). Finally, instead of running all tests (review/test/python) we can run only review/test/python/functional_tests and review/test/python/inspectors. But functional_tests is used only for checking if the tool runs correctly for different CLI configurations. Tests affecting the tool correctness only are in review/test/python/inspectors.

Please, change the production configuration for tests running.
