Task id can not be retrieved by the client side

[StonesGitHub]

Given the client and worker of celery might be deployed on different machines, to let the client side record the task id is very useful when locating problems. Currently, the client knows the task id, but it doesn`t reveal the info to the user. I suggest that it is better to expose the task id info to the user who calls a celery client submitting Pls consider it.

I try to kick a task1 in celery to kick task2, and task1 return task2.id, then Java can get task2.id......
