HTTP 413 Payload Too Large on Cloud Run due to 32MB payload Limit. #220

I'm trying to set up attic on cloud run. And I'm encountering an annoying issue.
During push of some packages, I get:

This is due to cloud run having a 32MB payload limit. See https://cloud.google.com/run/quotas#cloud_run_limits .
As far as I know, there are basically 3 ways to fix this problem:

Switching the cloud run instance to HTTP/2. As there is no size limit for HTTP/2 requests. But currently attic does not seem to support HTTP/2 servers (at least curl -i --http2-prior-knowledge https://my-atticd.us-central1.run.app returns upstream connect error or disconnect/reset before headers. reset reason: connection termination)
Using signed urls with GCS.
Splitting the upload into 32MB chunks and doing multipart upload?

How could we fix that the easiest way?
