Cloudkitty has a default (built-in the container) metrics.yml file
 in the /etc/cloudkitty/metrics.yml files. We would like to be able
 to overwrite/customize these metrics configurations via kolla-ansible.
 Cloudkitty is able to use a custom metric file via "metrics_conf".
 Therefore, we are enabling this configuration via Kolla-ansible.
