There must be other OpenStack services which have also faced this ‘stop scheduling but keep replying’ issues. Can we make the names for the various states and transitions consistent ?

The maintenance use case was mentioned: I want to evacuate routers/dhcp-servers from a host before taking it down, and having the scheduler add new routers/dhcp while I'm evacuating the node is a) an annoyance, and b) causes a service blip when I have to right away move that new router/dhcp to another host. The other use case is adding a new host/agent into an existing environment. I want to be able to bring the new host/agent up and into the neutron config, but I don't want any of my customers' routers/dhcp-servers scheduled there until I've had a chance to assign some test routers/dhcp-servers and make sure the new server is properly configured and fully operational. These are all solid reasons for adding this, and it makes sense to me as well. From a deployers perspective, these would be a big win. Given we have already filed a bug, hopefully we can get this addressed soon.
