Plugin architecture about annif HOT 2 OPEN

In the current architecture these could simply be separate backends. Backends can register themselves using annif.backend.register_backend so I'm not sure whether the plugin infrastructure is really needed, but of course it would make Annif more extensible.

I have two systems where plugins are needed. One of them has a few mechanisms for plugins. This project is passing through an update, starting by getting a setup.py file, and making more use of vanilla features.

We are thinking about using simple entry points (other good doc from setuptools).

I believe PyTest and PyLint use this approach. Scrapy is a different beast, so they used a different approach to allow scrappers to easily extend scrapy, without the need to package a python utility with setuptools.
