[FLINK-5703][runtime]Job manager failure recovery via reconciliation with
TaskManager reports
This is part of [Non-disruptive JobManager Failures via Reconciliation
](https://issues.apache.org/jira/browse/FLINK-4911).
The design doc for this part is attached in the JIRA and it mainly contains
the following work:
- **RECONCILING** state transition for job status and execution.
- The data structure recovery for **ExecutionGraph**,
**ExecutionVertex**,**Execution** based on **TaskManager** reports.
Two parts are left for the whole feature:
- The related modifications in **TaskManger** side will be submitted in
another JIRA, including not cancel the tasks when notified job leader changed
and report the task status to **JobManager**, etc.
- This PR will not make an effect on the current master branch, so it is
safe to merge. The reconcile logic should be triggered by **JobManagerRunner**
when grants leadership, but it is dependent on [Determine whether the job
starts from last JobManager
failure](https://issues.apache.org/jira/browse/FLINK-5501) , so I will modify
the **JobManagerRunner** logic after
[FLINK-5501](https://issues.apache.org/jira/browse/FLINK-5501) is merged.
