This patch implements a new stats collector paradigm
which uses the typing Protocol. Any object that wants to
supply stats to the collector has to implement the
aprsd.stats.collector.StatsProducer protocol, which at the
current time is implementing a stats() method on the object.
Then register the stats singleton producer with the collector by
calling collector.Collector().register_producer()
This only works if the stats producer object is a singleton.
This patch is the initial conversion of the custom config
and config file yaml format to oslo_config's configuration mechanism.
The resulting config format is now an ini type file.
The default location is ~/.config/aprsd/aprsd.conf
This is a backwards incompatible change. You will have to rebuild
the config file and edit it.
Also any aprsd plugins can now define config options in code and
add an setup.cfg entry_point definition
oslo_config.opts =
foo.conf = foo.conf:list_opts
