What changed?
A large but simple refactoring for history task key type:
Why?
This is to prevent misuse of history task key. Especially for immediate task key, when we store the key into database, we convert the timestamp to unix nanoseconds. To unify the logic of type conversion for immediate task key and scheduled task key, we set the scheduled time of immediate keys to unix 0 timestamp to avoid handling zero timestamp in golang.
