Resteasy connector ignores SSLContext

[ThomasBri]

The Resteasy connector does not check whether the HttpRequest's Config object has an SSLContext.
Other connectors perform this check e.g. the httpclient connector.

Therefore something like this

Config config = Config.newConfig();
config.withSSLContext(sslContext);
OSClient os = OSFactory.builderV3().withConfig(config)

does not work as expected.
