Merge "Expose public_protocol parameter in openstack::controller"
Adds Support for Debug Logging

Previously, debug logging was configurable for most openstack
classes.  This change adds the remaining classes that can be
configured for debug-level logging.

Defaults to false for backwards compatibility and to disable debug
level logging.
