Chalice deploy extremely slow: Overwhelming amount fo 'b "ZipFile" output

The `chalice deploy` is extremely slow, as in, it will take say 10-20 minutes to deploy, and each time I try, it shows an immense amount of code in the terminal, see below:

```

This continue for a few minutes, and happens everytime I try to deploy, even if a zip file is present in the `deployments` dir.

I have tried to run it with and without "pandas" and "numpy" in the requirements.txt, still the same situation.

Start by reproducing the issue with the `chalice deploy` entry point and inspect the verbose terminal output around the `UpdateFunctionCode` request. Compare behavior with and without `pandas` and `numpy` in `requirements.txt`, and check whether an existing archive in `deployments` is reused; done means deployment completes without repeatedly printing the encoded `ZipFile` payload and without the reported delay.
