Use CUSTOM_PLUGIN_MODULE_PATHS

I've not been able to get this to work, getting errors like:

[Mon Apr 22 10:30:28.404964 2019] [wsgi:error] [pid 26766]   File "/usr/lib/python3.4/site-packages/satosa/plugin_loader.py", line 195, in _load_plugin_module
[Mon Apr 22 10:30:28.404967 2019] [wsgi:error] [pid 26766]     raise ValueError("Can't find module '%s'" % plugin_config["module"])
[Mon Apr 22 10:30:28.404977 2019] [wsgi:error] [pid 26766] ValueError: Can't find module 'satosa.micro_services.pairwise_generation.AddPairwiseAttribute'

NB:

https://github.com/IdentityPython/SATOSA/blob/master/doc/README.md says

CUSTOM_PLUGIN_MODULE_PATHS is a list of directory paths containing any front-/backend plugin modules

So that doesn't explicitly reference micro_services. And it says

It's possible to write custom plugins which can be loaded by SATOSA. They have to be contained in a Python module, which must be importable from the one of the paths specified by CUSTOM_PLUGIN_MODULE_PATHS in proxy_conf.yaml
