The change also implements blueprint agent-logging (this was due to the fact that the existing logging in the agents did not work with the change) Devstack support for the above is in https://review.openstack.org/10267 Notes: - The service and agent can be run with multiple configuration files by using the CLI parameters --config-file <filename> - The agent now makes use of the logging and debugging flags defined in quantum.conf. This follows the standard common configuration command line rules. Change-Id: I3bd7701526a950c360d7c2cf14b31045010b46ca
