    [FLINK-4912] Introduce RECONCILIATING state in ExecutionGraph and Exe…

    This is part of the non-disruptive JobManager failure recovery.
    
    Add a JobStatus and ExecutionState {{RECONCILING}}.
    If a job is started on a JobManager for master recovery, the job status 
with all the executions transition to {{RECONCILING}} state.
    
    From {{RECONCILING}}, execution can go to any existing task states 
(execution reconciled with TaskManager).

> This is part of the non-disruptive JobManager failure recovery.
> I suggest to add a JobStatus and ExecutionState {{RECONCILING}}.
> If a job is started on a that JobManager for master recovery (tbd how to 
> determine that) the {{ExecutionGraph}} and the {{Execution}}s start in the 
> reconciling state.
> From {{RECONCILING}}, tasks can go to {{RUNNING}} (execution reconciled with 
> TaskManager) or to {{FAILED}}.
