Fix: Handle gRPC precondition failures while creating object

[anushka567]

Description

This change addresses an issue identified in b/378625027 where gRPC precondition failures were not being handled correctly.

Previously, error handling only checked for HTTP status codes, but gRPC uses error code 9 for precondition failures. This update adds explicit handling for gRPC error code 9 to ensure proper detection and management of precondition failures in gRPC calls.

Additionally, gRPC tests are enabled for the rename_dir_limit test package to improve test coverage .

Note: Handling of rpc codes for the different flows will be taken seperately.
