venus deploymen fails when ProxySQL is enable

[Amos T.]

After enabling ProxySQL, when I run kolla-ansible -i deploy, the deployment throws the following fatal error at TASK [venus : Creating venus database].

fatal: [node-name]: FAILED! => {"action": "mysql_db", "changed": false, "msg": "unable to find /var/lib/ansible/.my.cnf. Exception message: (1045, \"ProxySQL Error: Access denied for user 'root'@'10.50.2.1' (using password: YES)\")"}
