gunicorn_config: Do not log UniqueViolation and StorageArgumentException to Sentry
- UniqueViolation is a lost cause, and the current solution is for clients to retry the request
- StorageArgumentException is a client error
therefore, neither should be logged by the swh-storage server to Sentry
Test Plan
Will fail because it depends on swh-core: swh-core!262 (closed)
