E2E workflow

[piotr-iohk]

Description

This PR introduces a GitHub Actions workflow for running end-to-end tests.
It can be triggered manually from the Actions UI or automatically on pull_request.

For now, it includes only a single test case:
Onboarding - Can start onboarding — mainly due to the current lack of testIDs in the app.

The e2e workflow:

• builds apk with E2E=true
• pulls e2e tests and regtest docker-compose config from https://github.com/synonymdev/bitkit-e2e-tests
• starts regtest and runs tests against built apk
• on failure, uploads a video and screenshot of test

To make the test work in the Android emulator environment I changed the Electrum server host to 10.0.2.2 (which maps to the host machine's 127.0.0.1 in the emulator).
It turns out that using 127.0.0.1 didn’t work after all in the GitHub Actions environment.

Worked with b466ed9. 🎉

Future PRs will expand test coverage as more testIDs are added.

So I am left wondering how could it work in the react native app 😱

PS. Wondering how will it work for LND, but I think we can also change from 0.0.0.0:9735 to 10.0.2.2:9735

Nice 👏🏻

I like the adb reverse fix 👏🏻 , with it, connecting to the LND peer from docker container should also work smooth. (not sure if it works tho'
