## What changes were proposed in this pull request?
The purpose of this PR to reflect the stage level blacklisting on the executor tab for the currently active stages.
After this change in the executor tab at the Status column one of the following label will be:
- "Blacklisted" when the executor is blacklisted application level (old flag)
- "Dead" when the executor is not Blacklisted and not Active
- "Blacklisted in Stages: [...]" when the executor is Active but the there are active blacklisted stages for the executor. Within the [] coma separated active stageIDs are listed.
- "Active" when the executor is Active and there is no active blacklisted stages for the executor
## How was this patch tested?
Both with unit tests and manually.
#### Manual test
Spark was started as:
```bash
bin/spark-shell --master "local-cluster[2,1,1024]" --conf "spark.blacklist.enabled=true" --conf "spark.blacklist.stage.maxFailedTasksPerExecutor=1" --conf "spark.blacklist.application.maxFailedTasksPerExecutor=10"
```
And the job was:
```scala
import org.apache.spark.SparkEnv
val pairs = sc.parallelize(1 to 10000, 10).map { x =>
if (SparkEnv.get.executorId.toInt == 0) throw new RuntimeException("Bad executor")
else {
Thread.sleep(10)
(x % 10, x)
}
}
val all = pairs.cogroup(pairs)
all.collect()
```
UI screenshots about the running:
- One executor is blacklisted in the two stages:
- One stage completes the other one is still running:
- Both stages are completed:
### Unit tests
In AppStatusListenerSuite.scala both the node blacklisting for a stage and the executor blacklisting for stage are tested.
