When deploying Kibana with the default configuration of openstack_cacert
being unset, it fails due to an invalid configuration. The error message
is both unfriendly and useful:
"message":"child \"elasticsearch\" fails because [child \"ssl\" fails
because [child \"certificateAuthorities\" fails because [single value of
\"certificateAuthorities\" fails because [\"certificateAuthorities\"
must be a string]]]]"}
This is because we set elasticsearch.ssl.certificateAuthorities even
when there is no CA cert configured.
This change fixes the issue by only setting
elasticsearch.ssl.certificateAuthorities when a CA cert is configured.
