CTM-381:Always send the workspace google project to the DRSHub request body

[LizBaldo]

Jira Ticket: https://broadworkbench.atlassian.net/browse/CTM-381

All TDR clients via DRSHub should now pass the Google Project ID of the requester so the DRSHub resolution can then be billed appropriately if requester pay is enabled.

I remember there being some special handling for AnVIL URIs in here, should that now be removed?

The special handling was for something slightly different actually and I think it should remain in there

The way requester pay works with notebooks is actually different than what i thought initially:

When a requester pays URI is detected (e.g. drs://dg.ANV0...), this hits the Rawls API — not DRSHub — to enable requester pays for the workspace's linked service accounts.
After DRSHub returns the GCS location and credentials, the billing_project (google project id) is used in:
-- gs.get_signed_url(..., requester_pays_user_project=billing_project)when generating a signed URL fallback
-- GSBlob(info.bucket_name, info.key, info.credentials, billing_project) passed into the blob for direct GCS reads/copies
