Fix default values so they work in a devstack run

This commit fixes errors with the default values used in config.py
Previously, an incorrect default could potentially be masked in a
gate run by putting the correct value in the sample config. However,
by moving to an auto-generated sample config file the defaults set
in config.py will be used, exposing these mismatches.

Partially Implements: blueprint config-cleanup
