[zun][zun_api][blazar][config][yoga][kolla-ansible] Adding more configuration to config file

Hi all, I am playing around with Zun. I have used kolla-ansible as a deployment tool for deploying the yoga version of OpenStack. I am trying to add an option to the configuration file. However, those added options are not recognized by OpenStack when being called. For instance, Zun.conf, I am adding a new database (blazar) information to it so I can access blazar information in the zun service. Would that be possible to allow the zun_api container to access the blazar database? Thanks for your help, James
