Package Python wrappers sources

Guillaume Paserorequested to merge
pkg_python_wrappers into develop

By installing and packaging the minimal sources for the Python extension _otbApplication, it is possible to recompile this binary for different Python versions (the extension is linked to libpythonXY.so).

This operation can be done by a user after isntalling a standalone package, in order to recompile bindings for his specific Python version.

Finally, this feature is a first step to generate Python Wheels for OTB bindings.
