555 only include xhr and fetch performance timings by default more is opt in

[codecapitano]

Why

The Faro performance instrumentation processes and sends all resource entries emitted by the browsers resource timeline.
The number of entries emitted can grow very large depending on how resource heavy a web app/site is.
This can be hundreds of items and more per user session!

Most users are interested in initial load and render performance, web-vitals and xhr/fetch performance.
So we want to decrease resource consumption by only tracking the most necessary entries an make the rest opt-in

What

• Only track resources initiated by the fetch method or xhml-http-request i. e. initiatorType: xmlhttprequest | fetch
• Allow to enable tracking all resource entries or to disable tracking of resource items
