[SPARK-13501] Remove use of Guava Stopwatch.
Our nightly doc snapshot builds are failing due to some issue involving the
Guava Stopwatch constructor:
```
[error]
/home/jenkins/workspace/spark-master-docs/spark/core/src/main/scala/org/apache/spark/scheduler/cluster/mesos/CoarseMesosSchedulerBackend.scala:496:
constructor Stopwatch in class Stopwatch cannot be accessed in class
CoarseMesosSchedulerBackend
[error] val stopwatch = new Stopwatch()
[error] ^
```
This Stopwatch constructor was deprecated in newer versions of Guava
(https://github.com/google/guava/commit/fd0cbc2c5c90e85fb22c8e86ea19630032090943)
and it's possible that some classpath issues affecting Unidoc could be causing
this to trigger compilation failures.
In order to work around this issue, this patch removes this use of
Stopwatch since we don't use it anywhere else in the Spark codebase.
