Currently, b2c ods start, b2c ods stop , b2c ods restart do not support synchronous execution. Unlike sfcc-ci, which provides a --sync flag, b2c only supports --wait on the ods create command.
This makes it difficult as there is no way to wait for the operation to complete or confirm success. Support for --wait (related timeout/polling behavior) should be added to ods start, stop, restart
