Description

Flink-5892 introduced the job manager / checkpoint coordinator part of managing state on the operator level instead of the task level by introducing explicit operator_id -> state mappings. However, this explicit mapping was not introduced in the task manager side, so the explicit mapping is still converted into a mapping that suits the implicit operator chain order.

We should also introduce explicit operator ids to state management on the task manager.
