[services-lib][blob-client] Revoke holder after upload failure
Summary:
Our upload process is two-step. If the second step fails, we should revert the first step.
We want to revoke the holder (revert 1st step) after a failure to upload a blob (2nd step).
Test Plan: Artifically failed upload. Ensured that holder isn't there.
