docs: Use sphinx-apidoc library for autodoc generation

This package is used for automatic generation of autodoc
documentation which offers the following advantages:

* the Patrole framework for all modules is always built
  and kept up to date
* it is isolated in its own page layout
* it can still be linked to by other documentation pages
  easily
