[SPARK-2017][WebUI]Defer executing drawTaskAssignmentTimeline until page
loaded to avoid to freeze the page
When there are massive tasks in the stage page (such as, running
`sc.parallelize(1 to 100000, 10000).count()`), `Event Timeline` needs 15+
seconds to render the graph (drawTaskAssignmentTimeline) in my environment. The
page is unresponsive until the graph is ready.
However, since `Event Timeline` is hidden by default, we can defer
`drawTaskAssignmentTimeline` until page loaded to avoid freezing the page. So
that the user can view the page while rendering `Event Timeline` in the
background.
This PR puts `drawTaskAssignmentTimeline` into `$(function(){})` to avoid
blocking loading page.
This is only a partial fix for SPARK-2017.
