Serde be functional interface)

> {{Serializer}}, {{Deserializer}} and {{Serde}} interfaces have methods 
> {{configure()}} and {{close()}}. Pretty often one want to leave these methods 
> empty. For example, a lot of serializers inside 
> {{org.apache.kafka.common.serialization}} package have these methods empty:
> {code}
> @Override
> public void configure(Map configs, boolean isKey) {
> // nothing to do
> }
> @Override
> public void close() {
> // nothing to do
> }
> {code}
> To avoid such boilerplate, we may create new interfaces (like 
> {{UnconfiguredSerializer}}), in which we will define these methods empty.
