Code Review
This pull request adds support for deleting source objects after a successful composition operation in Google Cloud Storage. This is implemented by adding a DeleteSourceObjects field to the Composer struct, which is propagated through both HTTP and gRPC clients. Integration and unit tests are added to verify this behavior. The review feedback highlights a potential resource leak in the integration tests if the compose operation fails before the deferred deletions are registered, suggesting a robust cleanup function using context.WithoutCancel.
