I have updated the patch (https://review.openstack.org/#/c/189391/) to implement the above. I have it marked WIP because it doesn't have any tests and it modifies ServicePluginBase to have a call to get_processes(), but almost no service plugins actually inherit from it even though they implement its interface. The get_processes stuff in general could be fleshed out a bit as well. I just wanted to get something up for the purposes of discussion, so anyone interested in this particular problem should take a look and discuss. :)
