Modify api and rpc default number of workers
- Limit number of api workers to roughly using half of system
RAM. Spawning a bunch, just to have the OOM killer nuke them
regularly is not useful.
- Bump the rpc_workers default to half of the api_workers.
A default of 1 falls behind on any reasonably sized node.

Title:
api and rpc worker defaults are problematic
Status in neutron:
Fix Released
Bug description:
We default the number of api workers to the number of cores. At
approximately 2GB per neutron-server, sometimes that's more RAM than
is available, and the OOM killer comes out.
We default the number of rpc workers to 1, which seems to fall behind
on all but the smallest deployments.
