…onfiguration

Right now we make at most 2N calls to the Tron API during config
deployments: N to get the current configs and at most N if all services
have changes.

To start, I'd like to reduce this to N by allowing GET /api/config to
return all the configs so that the only requests needed are POSTs for
changed configs.

Depending on how this goes, we can look into batching up the POSTs so
that we can also do that in a single request.

In terms of speed, it looks like loading all the configs from pnw-prod
(on my devbox) with this new behavior takes ~3s - which isn't great, but
there's a decent bit of file IO going on here :(
