Fix Version/s: 1.2.0 beta 3
Currently they have different names but use the same option names, which doesn't make sense for two reasons:
- internode_encryption: none/all doesn't make sense for client encryption. Should be 'enabled: true/false'
- truststore and truststore_password are not used by Cassandra for client encryption and shouldn't be present in client_encryption_options.
Moved type-dependent options to either ServerEncryptionOptions or ClientEncryptionOptions. Left truststore and truststore_password in EncryptionOptions for use by Stress and CLI (but removed them from cassandra.yaml).
