Allow loading multiple models at the same time

[cchudant]

Description

The upload_model request will return a UUID for the model. This UUID will be used by run_model and will be added to the signed response proofs.

We may want to be backward compatible with the way our docs and blogposts are written, so that if the model name is not provided, you just use the last one that was uploaded.

Future work

• Method to remove a model from the server.
• Save the models on disk. Should we ship everything at once or can we ship multiple models without these?

Motivation and Context

Right now, once you upload a model, you won't be able to upload another one without discarding the first.
