Consider how to provide SSL from ConnectionDetails

[philwebb]

We would like to extend our ConnectionDetails abstraction to allow SSL based connections. The following two issues are blocked on this design work:

• Improve Elasticsearch ServiceConnection #35926
• Allow Kafka Admin Client's security protocol to be configured when using custom KafkaConnectionDetails #38342
• Testcontainer Redis with having ssl:true in application.yml #43977

I've looked at our ConnectionDetails and the properties and came up with that list:

SSL support possible:

There are already properties to configure the SSL bundle to use.

• RabbitConnectionDetails
• CassandraConnectionDetails (i have a PoC for that)
• CouchbaseConnectionDetails
• RedisConnectionDetails
• ElasticsearchConnectionDetails
• KafkaConnectionDetails
• MongoConnectionDetails

SSL support not possible

SSL support with those is not possible (at least not without extending properties), as the properties don't allow for SSL configuration via a SSL bundle:

• OtlpLoggingConnectionDetails
• OtlpMetricsConnectionDetails
• OtlpTracingConnectionDetails
• ZipkinConnectionDetails
• FlywayConnectionDetails
• JdbcConnectionDetails
• ActiveMQConnectionDetails
• ArtemisConnectionDetails
• LdapConnectionDetails
• LiquibaseConnectionDetails
• Neo4jConnectionDetails
• PulsarConnectionDetails
• R2dbcConnectionDetails
