[DISCUSS] When task retry strategy, merge task instance
hello, friends!
When task retry strategy, it is recommended to merge task instance.
At present, retry every time, a new task instance will be created, and increase retry count by one.
I think, no need to create a new task every time, only increase retry count by one.
The purpose of this is to facilitate query and statistics.
Now:

If add condition by retry_times = 0, I won't see any subsequent retry tasks,
Can't see the current status of the retry task.
I think retrying the task should not create a new task.

good idea, but I think task instance should generate a new one every time
when it indeed runs. If there is no newly generated task instance, some
person maybe will think there is a problem with the system. for your
situation maybe you could add the where condition by retry_times = 0?
