DM-34031: Add script for uploading raws.

[kfindeisen]

This PR creates a script that can reproducibly upload raws from ap_verify_ci_cosmos_pdr2. It assumes that gsutil is already installed and configured.

Can we call it prompt_prototype_upload_raws.sh? I'd like to move away from "proto" if we can.

Or should we call it prompt_prototype_upload_ci_cosmos_pdr2.sh, to make it very explicit where it's coming from?

@parejkoj is this better?

[parejkoj]

Thanks @kfindeisen . My only remaining question is whether we should name the script something related to the input data, e.g. prompt_prototype_upload_ci_cosmos_pdr2.sh?

[kfindeisen]

I'd rather not. We might end up changing the backing dataset in-place, or we might upload multiple datasets from the same script.
