[test] Add Python NumPy library check and build CSCS test on top of it

[hurricane642]

This is a continuation of the work on the test library. This PR work has been done with Numpy tests. A new file base_check.py has been added, introducing the main class for the Numpy test, as well as the CSCS tests inherited from it.

I did the following changes:

• Removed the documentation for executable etc. I don't think it makes sense to document them, unless they are required.
• I moved the test in the library under hpctestlib/python
• I documented the performance functions and used s as units.
