Comment 1 for bug 1240197

I was looking for something to implement as my first patch and this sounds interesting. I did some poking around and found that nova uses Oslo.config which doesn't seem to support an `auto'-like feature. However, I do see this line[1] in nova/cmd/all.py -

    launcher.launch_service(server, workers=server.workers or 1)

which essentially starts worker processes. Does it make sense to detect the number of CPUs here and set that instead of 1?
