Summary

Created a blob submodule in Identity for blob service actions.
Created function that calls Blob remove-multiple-holders endpoint for all holders prefixed by given device IDs.
Used exponential backoff to retry eventual failed holders.

Depends on D13648, D13649, D13643

Test Plan

Took a test from D13648 test plan, moved to Identity and called the new function in place of the direct BlobServiceClient call

32–35	This causes instant failure return when `await?` returns err, ignoring exponential backoff. I'm wondering if sth like this wouldn't be better: let remaining = match blob_client.remove_multiple_holders(request.clone()).await { Ok(response) => response.failed_requests.into(), Err(_) => request, }; So we retry on HTTP call failure too.
