[zun] allow zun to get information from blazar database

Hi all, I am using kolla-ansible for OpenStack deployment in the yoga version. Is It possible to allow zun to retrieve information from the blazar database in zun_api container? I have tried to include the blazar database connection information in the zun.conf file. However, when I try to use the newly added blazar information, I am getting the following error message.

oslo_config.cfg.NoSuchOptError: no such option connectionTest in group [database]

It seems like I have to set up some option somewhere else in the code. But I was not able to identify them.

Thanks for your help James
