support llama2 13b train and inference pipeline in fastchat (#73)

* support qlora mistral training

* added deep speed to requirements

* temporary save for switching disk region

* added shuffle and access token

* finished training pipeline; need to fix inference

* finished training pipeline; need to fix inference

* fixed inference pipeline

* commiting to test deepspeed

* added featurere to remove seq longer than 2048

* try to merge

* minor changes

* minor changes
