Add SslOptions support to JedisClientConfiguration

[gggeon96]

Description

Adds SslOptions support to JedisClientConfiguration for consistency with the existing SSLSocketFactory, SSLParameters, and HostnameVerifier options, as discussed in #3355.

JedisClientConfiguration.builder()
    .useSsl()
    .sslOptions(SslOptions.builder()
        .truststore("truststore.p12", "secret")
        .sslProtocol("TLSv1.3")
        .build())
    .build();

The Mutable cleanup follows your direction: the sslSocketFactory, sslParameters, and hostnameVerifier fields/setters had no invocations, so they are removed; the corresponding getters now return Optional.empty().

Open question

I used @since 4.1 as a placeholder — happy to retarget to whichever release line you prefer.

Closes #3355
