Set SSL CA Cert Pem via In-memory

Description

I’m trying to replace the file paths to in-memory certs, but i was not able to figure out how to set SslCa pem content from in-memory. I only see SslCaLocation property and there is no equivalent SslCaPem property

How to reproduce

producerConfig = new ProducerConfig
                {
                    BootstrapServers = "<<servers with ports in csv>>",
                    Acks = Acks.All,
                    SecurityProtocol = SecurityProtocol.Ssl,
                    SslCaLocation = "root-ca-chain.pem",
                    SslCertificatePem = "<<Public Cert pem file content>>",
                    SslKeyPem = "<<private cert pem file content>>",
                    EnableSslCertificateVerification = true,
                    ClientId = "test", 
                    Debug = "broker,topic,msg"
                };
                using (var producer = new ProducerBuilder<Null, string>(_producerConfig).Build())
                {
                    var response = await producer.ProduceAsync(topic, new Message<Null, string> { Value = request });
                }

It was simply omitted to cut down scope. We’ll address this after the v1.6.0 release.
