Allowing setting Chrome bandwidth and latency setting

[mitar]

Current behavior:

Currently, during CI, the client-side connects to local server-side and this makes all API calls very fast. But in production, users are not so close to the server and I would prefer if I could test a more realistic scenario where there is a bandwidth and latency limits.

Desired behavior:

In Chrome, in web development tool, you can configure the speed and latency override for all HTTP requests. I think it would be great if one could control this from tests in Cypress (or for all tests, or just for some). So that I could also test if on a very slow links behavior is as expected (for example, to test that loading UI element appears and so on).

The features requested in this issue are now possible as part of cy.route2().

cy.route2() is currently experimental and requires being enabled by passing "experimentalNetworkStubbing": true through your Cypress configuration. This will eventually be merged in as part of our standard API.

Please see the cy.route2() docs for full details: https://on.cypress.io/route2

If you encounter any issues or unexpected behavior while using cy.route2() we encourage you to open a new issue so that we can work out all the issues before public release. Thanks!
