[RCF] Serialize|Deserialize thrift message on demands (support protobuf's fieldmask) | 支持 thrift 按需序列化（支持 pb fieldmask)

[AsterDY]

Protobuffer provides an ability called FieldMask to serialize|deserialize message on demands. And Netflix has used it in practice to improve the performance of API services: https://netflixtechblog.com/practical-api-design-at-netflix-part-1-using-protobuf-fieldmask-35cfdc606518. As for thrift, there is no such a direct support -- we can define a trimmed mirror IDL for every client as a workaround, but it is unsuitable for large-scale application development that every client must main a specified code-gen product for the trimmed IDL. In contrast, It is a trend to use a common repo to maintain code-gen products nowadays, and under such a situation, the overhead of redundant fields will get higher and higher. Therefore, we need to propose a way to support fieldmask to achieve serializing|deserializing messages on demands.
