cenyuhai cc87280fcd [SPARK-17171][WEB UI] DAG will list all partitions in the graph
## What changes were proposed in this pull request?
DAG will list all partitions in the graph, it is too slow and hard to see all graph.
Always we don't want to see all partitions,we just want to see the relations of DAG graph.
So I just show 2 root nodes for Rdds.

Before this PR, the DAG graph looks like [dag1.png](https://issues.apache.org/jira/secure/attachment/12824702/dag1.png), [dag3.png](https://issues.apache.org/jira/secure/attachment/12825456/dag3.png), after this PR, the DAG graph looks like [dag2.png](https://issues.apache.org/jira/secure/attachment/12824703/dag2.png),[dag4.png](https://issues.apache.org/jira/secure/attachment/12825457/dag4.png)
