[SPARK-15235][WEBUI] Corresponding row cannot be highlighted even though cursor 
is on the job on Web UI's timeline

## What changes were proposed in this pull request?

To extract job descriptions and stage name, there are following regular 
expressions in timeline-view.js

```
var jobIdText = $($(baseElem).find(".application-timeline-content")[0]).text();
var jobId = jobIdText.match("\\(Job (\\d+)\\)")[1];
...
var stageIdText = $($(baseElem).find(".job-timeline-content")[0]).text();
var stageIdAndAttempt = stageIdText.match("\\(Stage 
(\\d+\\.\\d+)\\)")[1].split(".");
```

But if job descriptions include patterns like "(Job x)" or stage names include 
patterns like "(Stage x.y)", the regular expressions cannot be match as we 
expected, ending up with corresponding row cannot be highlighted even though we 
move the cursor onto the job on Web UI's timeline.

## How was this patch tested?

Manually tested with spark-shell and Web UI.
