test: mitmproxy + low bandwidth + automated QA using detox

[rahimrahman]

Summary

Update E2E iOS Detox Test to have the ability to run in a low-bandwidth environment using similar label on PR. A new label has been introduced called E2E iOS tests for PR (LBW 1). The idea is to be able to create multiple profile (LBW 1-n) and change the bandwidth speed + ping time.

Ticket Link

https://mattermost.atlassian.net/browse/MM-60378

TODOs

• fixing some bandwidth lowering flakiness.
• finalize version of the action files to be reusable. Create a low-bandwidth composite/reusable workflow to be ran if the runner is set for low-bandwidth (perhaps pass using env variable?)
• create a trigger for testing using detox on low-bandwidth. We have E2E iOS tests for PR to start the test. Maybe we can use E2E iOS tests for PR (low bw).
• Changes to certain timeouts because the current detox test has a 1s timeout while waiting for elements to show up (or else it would consider the test to fail). With low bandwidth (at 1s ping), all test will fail, so the test timeout would have to evolve. We can just replace the timeout constant if runner is doing low bandwidth test.

Checklist

• Added or updated unit tests (required for all new features)
• Has UI changes
• Includes text changes and localization file updates
• Have tested against the 5 core themes to ensure consistency between them.
• Have run E2E tests by adding label E2E iOS tests for PR.

Release Note

[mvitale1989]

Thank you for the changes Rahim, lgtm overall! I have left a few comments with some suggestions.

Also I was looking up to check if the throttling could be done directly with mitmproxy, instead of changing the host network config, and found your comment in the related issue, which was awesome 😄 🙌

Thanks Rahim, the only needed change to avoid a confusing users would be around adding the label name to the concurrency group, please check this comment
