[SPARK-15373][WEB UI] Spark UI should show consistent timezones.

## What changes were proposed in this pull request?

Currently, SparkUI shows two timezones in a single page when the timezone of browser is different from the server JVM timezone. The following is an example on Databricks CE which uses 'Etc/UTC' timezone.

- The time of `submitted` column of list and pop-up description shows `2016/05/18 00:03:07`
- The time of `timeline chart` shows `2016/05/17 17:03:07`.

![Different Timezone](https://issues.apache.org/jira/secure/attachment/12804553/12804553_timezone.png)

This PR fixes the **timeline chart** to use the same timezone by the followings.
- Upgrade `vis` from 3.9.0(2015-01-16)  to 4.16.1(2016-04-18)
- Override `moment` of `vis` to get `offset`
- Update `AllJobsPage`, `JobPage`, and `StagePage`.

## How was this patch tested?

Manual. Run the following command and see the Spark UI's event timelines.

```
$ SPARK_SUBMIT_OPTS="-Dscala.usejavacp=true -Duser.timezone=Etc/UTC" bin/spark-submit --class org.apache.spark.repl.Main
