Tim Simmons 81ce132e90 Worker Model
- More information about the actual worker code can be found
  in `designate/worker/README.md` and in the inline docstrings

- Stand up a `designate-worker` process with an rpcapi, all
  the usual jazz

- Implement a base `Task` class that defines the behavior of
  a task and exposes resources to the task.

- Implement CUD Zone tasks, which includes Tasks that poll for zones,
  send Notifies, and update status. These are all done in parallel
  with threads using a shared threadpool, rather than iteratively.

- Implement a `recover_shard` task that serves the function
  of a periodic recovery, but only for a shard. Call that
  task with various shards from the zone manager.

- Put some shims in central and mdns so that the worker can
  be switched on/off with a few config values.

- Changes Zone Manager -> Producer
    - Removes zm rpcapi
    - Adds startable designate-producer service
    - Makes zone-manager an alias for producer service with a warning log
    - Lots of renaming

- Moves zone export to worker
    - API now uses central_api.export_zone to get zonefiles
    - Central uses worker_api.start_zone_export to init exports
    - Now including unit tests
    - Temporary workarounds for upgrade/migration move the logic
      into central if worker isn't available.

- Deprecates Pool manager polling options and adds warning msg on
  starting designate-pool-manager

- Get some devstack going

- Changes powerdns backend to get new sqlalchemy sessions for each
  action

- Sets the default number of threads in a worker process to 200,
  this is pretty much a shot in the dark, but 1000 seemed like
  too many, and 20 wasn't enough.

- Grenade upgrade testing

- Deprecation warnings for zone/pool mgr

The way to run this is simple, just stop `designate-pool-manager`
and `designate-zone-manager`, toggle the config settings in the
`service:worker` section: enabled = true, notify = true
and start `designate-worker` and `designate-producer` and you
should be good to go.
