Need the option to connect using SSL for CQL Cassandra Driver

[ckamaleo]

Describe the feature:
For connecting to Yugabyte CQL DB we use --ssl and provide a certfile. Unfortunately, we don't see any option in JanusGraph to specify the certfile.

https://github.com/JanusGraph/janusgraph/blob/master/janusgraph-dist/src/assembly/cfilter/conf/janusgraph-cql.properties

Describe a specific use case for the feature:
Can we add the Feature to Support CQL SSL Connections?

Please, check options under ‘storage.cql.ssl’ namespace: https://docs.janusgraph.org/configs/configuration-reference/
