Fix print format of fewshot (#474)

* "add mlm params to dygraph ernie1.0"

* finish p-tuning v1.0

* mend

* delete unused coment

* add label_normalized

* P-tuning: support Chid task of FewCLUE

* 1. decouple evaluate and train

* 1.add FewCLUE datasets(9/9)
2.implement p-tuning strategy by transform_function
3.unify train_script beteween `chid` task and other 8 tasks of FewCLUE

* add README.md

* update FewCLUE data

* add predict.py for FewCLUE

* update README

* update README.md

* add FewCLUE 9 datasets

* update dataset Name

* Tiny fix
