Improve Serializer

[alalag1]

Motivation

Interface spec of HttpBodySerializer

    @Override
    default boolean supportsRead(MediaType mediaType, Type type) {
        return true;
    }

    @Override
    default boolean supportsWrite(MediaType mediaType, Type type) {
        return true;
    }

    byte[] serialize(Object target) throws Exception;

    <T> T deSerialize(byte[] data, Type type) throws Exception;

Problem is that the end-user do not know how to serialize/deserialize after calling supportsRead(MediaType mediaType, Type type) because parameters of MediaType and Type is not passed in serialize() and deSerialize()

Improvement

1. Pass MediaType and Type in serialize() and deSerialize()
   It is easy to do this, but the end-user may need to do the parameters check twice, which is not good for performance.
2. Remove supportsRead() and supportsWrite()
   This would be good for performance but it would be hard to design the serialize() and deSerialize().
