Markus Zoeller 627fde8832 single point of entry for sample config generation
To create a "nova.conf.sample" file, we use "tox -e genconfig".
This command triggers the generator from "oslo.config" which needs
entry points in "setup.cfg". Right now we have multiple entry points
to "opts.py" files which are going to be consolidated to one single
point of entry "nova/conf/opts.py". Until all config options are
moved to that central place, we would often face merge conflicts
when multiple contributors commit patches to that one "opts.py".

To prevent that, and to make it easier for future config option
moduls in "nova/conf/", the new "nova/conf/opts.py" module collects
the config options in a dynamic way.
