feat(python): Add option to change the python binary (#1297)

Browse Source 
* Add option to change the python binary

We are going to start to have problems with the python binary as python2
is removed and replaced with python3. To make the transition easier I
have added an option to the python module to allow the user to pick a
particular binary, e.g `python3`, for the module to use when selecting
the version of python. I have also refactored the python tests moving
almost all of them into the module and removing the dependency on the
version of python that is installed on the system.

* Add advanced config section to python module docs

Have added an advanced config section to the python module docs and
moved the `python_binary` option into that section.
