Which ini file is active is a function of the packaging so it's upto
the RPM and DEB folks notOpenStack upstream. teh
/etc/neutron/plugin.ini abstraction is the RPM way, which I personally
 like a bit better than the DEB way.

What IU have discovered is is since all teh ini files specified on the
lauch command line are sourced in teh same way it doesn't make any
technical different if it's in /etc/neutron/plugin.ini
/etc/neutron/plugins/ml2/ml2.ini or even /etc/neutron/neutron.conf
(well except that breaking it into some different files means
different service can start with different config values, can't think
if that's actually useful now but it's good abstraction)

If started with debug=true, on restart the service will log all the
config settings it has read, for example:

2014-07-10 14:01:09.385 20138 DEBUG
neutron.plugins.openvswitch.agent.ovs_neutron_agent [-]
===================
=============================================================

allow_overlapping_i
ps          = False log_opt_values
/usr/lib/python2.7/dist-packages/oslo/config/cfg.py:1941

and so on for all sorts of options, grep that log for 'core_plugin'
and you'll see what you're using:

2014-07-10 14:01:09.390 20138 DEBUG
neutron.plugins.openvswitch.agent.ovs_neutron_agent [-] core_plugin
            = ml2 log_opt_values
/usr/lib/python2.7/dist-packages/oslo/config/cfg.py:1941

It's still quite a mess.  Took me an afternoon to understand and test
upgrade for all other OpenStack components, going on 2 weeks of more
than full days just trying to get Neutron to go again and I'm still
not all the way there.
