[SPARK-18364][YARN] Expose metrics for YarnShuffleService
Registers the shuffle server's metrics with the Hadoop Node Manager's
DefaultMetricsSystem.
## What changes were proposed in this pull request?
Expose the shuffle service metrics not only on the ExternalShuffleService
as done in SPARK-16405, but also in the YarnShuffleService. Because the YARN
Node Manager operates under
## How was this patch tested?
Manual deploy of new yarn-shuffle jar into a Node Manager and verifying
that the metrics appear in the Node Manager-standard location. This is JMX
with an query endpoint at `/jmx`.
Resulting metrics look like this:
```
[user@host ~]$ curl -sk -XGET https://`hostname -f`:8042/jmx | jq . | grep
'shuffleservice' -B 1 -A 18
