Clean up nova/conf/scheduler.py
Clean up nova/conf/scheduler.py

Originally this patchset had moved the handling of the config options
from nova/scheduler/opts.py, but commit
627fde88321b67c8ffbb2062dba7a13912f33a74 incorporated that change,
leaving this smallish patch that cleans up some of the naming in the
nova/conf/scheduler.py file.
