Store profile auth/config data on pods

`allSet` will now look up the profile's pod ID and send it over there if
necessary.
Remove debug output
Add endpoint to clear pod profile configs

Rounding out our CRUD on remote profiles. This will send an HTTP `DELETE` to the
pod containing a profile we want to clear config data on. Though philosophically
that should delete the whole profile, we never actually want that to happen. We
would lose track of a lot of data, and wiping `auth` would break syncing for all
apps authorized to see that profile. So `DELETE /profile` only clears the
`config` object, just like `reset` has always done locally.
Hook up pipeline inject to pods and nexus
Use port config again in podClient

The default is `8070` nonsecure. Production config should be set to `443`
secure.

Fix the call name

Tell pods to sync tasks upon auth

We were still trying to do this locally, which is not helpful when the workers
live in the pod.
Use JSON

Oops
Initialize nexusClient from hallwayd

It needs a Redis connection set up at boot for `getApp` to use.
Make acl fetch apps from the nexus

`taskman` determine which synclets to run based on the app data, which isn't
stored in pods. `acl.getApp` appears to be the single thing it needs to do its
work, so we're starting with that.

`nexusClient` exposes a function to get a list of apps, but it works the same
way as places that are fetching many already, so I'm not worrying about those
for now. We're likely going to want to fetch a bundle of apps in one request
soon anyway.

To decide whether `acl` should ask the nexus or look locally (because we _are_
the nexus), the simplest thing is to just tell `acl` what role we're running
under and switch on that. A result is that you **must** be running a nexus now
in order for anything to work. Because for the moment `nexus` and `apihost` are
sharing DB configs, writing the app data doesn't have to change yet.
