Link all requests to the page

[ankur22]

Feature Description

When a page navigates to a website, it will perform other resource requests to retrieve JS files, images etc. We are tracking each request as a metric in the form of browser_http_req_duration, browser_http_req_failed, browser_data_received and browser_data_sent. This is done here and here.

The issue is that we cannot link these metrics to the originating page. We need to find a way to link them with a shared id or page url. Issue with the page url is that the url for different pages could all be the same, so an id is preferred.

Suggested Solution (optional)

• Either a new ID that can be used with each new page.
• Link them to the trace.
• async groups api
