Fixes #8053

From another perspective, semantically returning busy is indeed more reasonable than error.

It is correct to change the response code, but we need more discussion on whether client should retry on this scenario. Personally I think the client should retry by default to avoid producing failure.

There has been a lot of discussion about whether system_busy should be retried. I personally support retrying. For details, please refer to #5845 @yuz10
