For now the primary goal with RPC is to remove Celery and RabbitMQ
from the stack, and I think we'd be better served by adding a single
new RPC call to the region, GetSecrets (say), so we can continue to
use the API from clusters. There are also some API calls that ship
more data than can fit in a single RPC payload, so we *need* this
anyway.
