Implements: blueprint designate-rolling-upgrade
- 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.

This change adds the tooling to use the DB Tables created for pool
config data and the tooling to migrate the config info itself.

We separate out the idea of targets (backends you write to), to places you read
from (DNS servers you query). This allows for backends like Akamai/Dynect/Agent
to work correctly with multiple DNS servers behind one target.
