原文基于fast.ai的ami，这里修改为AWS Deep Learning AMI

The AMI Ids for the Deep Learning (Ubuntu) AMI are the following:

• us-east-1 ami-405ade3a
• us-east-2 ami-f0725c95
• us-west-2 ami-f1e73689
• eu-west-1 ami-1812bb61
• ap-southeast-2 ami-5603eb34
• ap-northeast-2 ami-0ce14662
• ap-northeast-1 ami-329c2b54

注意：Deep Learning (Ubuntu) AMI 最少需要50G EBS空间

新增 fast_ai/stop_spot.sh 自动取消竞价请求并终止竞价实例
