DATAREDIS-427 - Allow construction of customized JdkSerializationRedisSerializer.

We now allow constructing JdkSerializationRedisSerializer using an own class loader and by specifying custom converters.

Using an own class-loader: new JdkSerializationRedisSerializer(classLoader)

Using own converters (Serializer/Deserializer): new JdkSerializationRedisSerializer(new SerializingConverter(), new DeserializingConverter(new DefaultDeserializer(classLoader)))
