in Kibana.yml file, there are the following ssl related settings:
#Optional settings that provide the paths to the PEM-format SSL certificate and key files.
#These files validate that your Elasticsearch backend uses the same key files.
#Optional setting that enables you to specify a path to the PEM file for the certificate
#authority for your Elasticsearch instance.
How to set them, i.e. how to relate them with corresponding certificate and key files of elasticsearch connected?
