[Synthetics] waterfall chart - handle cached resources (elastic#193089)
Browse files Browse the repository at this point in the history 
## Summary

Resolves elastic#184794

Ensures that the cached resources display accurate timing information on
the waterfall chart tooltips.

The information displayed should match the information displayed in the
flyout when the request url is clicked.

### Release note

Synthetics - resolves an issue for multi step browser journeys where
timings for cached resources within the same step were inaccurate within
the waterfall chart.

### Testing

1. Create a browser monitor with duplicate requests. For example: 
```
step("multi resource step", async () => {
    await page.goto('https://github.com');
    await page.goto('https://github.com');
    await page.goto('https://github.com');
})
```
2. Navigate to the monitor details page
3. Find the last test run panel, click the view test details button,
then click the view performance breakdown button

4. Scroll down to the waterfall chart. If you use github, requests after
about 115 should be cached. Note: some request may have been aborted and
their waterfall tooltip won't show. Find a request that was not aborted,
hover to see the tooltip, then click the request to view the flyout and
confirm the information.
