Connect to Google Cloud Storage

[ItamarSmirra]

Hi!
Is it possible to add another env variable for S3_HOSTNAME or something like that?
It is required for connecting the server to other storage host rather then AWS (Google for example);
Thank you!

Does AWS_S3_ENDPOINT work? For example:

AWS_S3_ENDPOINT=https://myendpoint.com:8080

It does seem to affect the connecting process and not returning the Invalid Credentials error, but now I am getting the following error:

Any ideas?

I did a little searching for that unspecific protocol error detected message and I believe it is because Google is picky about the http2 headers it receives. The AWS S3 library Rudolfs uses (Rusoto) might not be setting the correct http2 headers (like :scheme and :authority). See rusoto/rusoto#1985.

I'm not aware of anyone else successfully using Rudolfs with GCP via the S3 API. It would probably be better to add GCP support as its own backend.

I don't have any time to debug this further or implement GCP support, but I would be happy to shepherd any pull requests.
