I understand Justin's concern if we move /network and /images and /volume
to their own endpoints then it would be a change to the customer. I think
this could be solved by putting a proxy in front of each endpoint and
routing back to the appropriate service endpoint.
I added another image on the wiki page to describe what I'm trying to say.
I think might not be as bad of a transition since the compute worker would
receive a request for a new compute node then it would proxy over to the
admin or public api of the network or volume node to request information.
It would work very similar to how the queues work now.
