This commit creates the structure for migrating Designate
services from using eventlet, to using oslo.service threading backend
(standard/native python threading).
Key changes include:
* Eventlet isolation: existing eventlet-dependent service entrypoints
(central, mdns, producer, sink, worker, manage, status) are moved
from designate/cmd to a new designate/cmd/eventlet subdirectory.
* Updating their correct path in setup.cfg.
This prepares the codebase for future incremental migrations of
individual services to native threading.
