open source publishing code

Why ?

Wikipedia expressed interest into hosting the model themselves, so I'm sharing the code to push the model to AWS

How ?

The deploy.py script will:

1. create a docker image with a copy of fairseq nllb branch (the git clone isn't part of the script will add that to the readme), inference code, tokenizer model (sentencepiece)
2. push the docker image to AWS image registry
3. push the model weights to an S3 bucket
4. create a "sagemaker model" which is basically a tuple (docker image, model weights)
5. deploy the model to a "staging" Sagemaker endpoint

Test plan

Actually not tested. I used a slightly different version internally, but I've removed some hardcoded path/names from the script and I need to check if the Docker build still works
