Review comment:
for the time being, the reconcile loop gets into an error state if it
fails to create the checkpoint:
```reconciliationStatus:
error: 'java.util.concurrent.ExecutionException:
org.apache.flink.runtime.checkpoint.CheckpointException:
Checkpoint triggering task Source: Custom Source (1/2) of job
00000000000000000000000000000000
is not being executed at the moment. Aborting checkpoint. Failure
reason: Not
all required tasks are currently running.'
```
