GitHub actions - Ubuntu, Windows, and macOS

[kum-deepak]

The initial version, currently it runs our current test workflow on the latest Ubuntu, Windows, and macOS.

These should be possible to be extended to include OS/browser combinations that we intend to test.

Current config:

• Chrome, Firefox on Ubuntu
• Edge, Chrome, Firefox on Windows
• Safari, Chrome, Firefox on MacOS

Latest OS, Node 12

I have removed Saucelabs related settings.

Safari Headless is not supported with the NPM version of the plugin, so used from karma-runner/karma-safari-launcher#22

Wow, this is great!

It's funny that it runs all the tests twice, once for push and once for pull_request, but I guess that is normal.

Edit: I see, that's because you had to create the branch on the main repo in order to test actions, so it's testing push to the main repo as well as the PR.

This is much faster too!

What a relief to be done with unreliable saucelabs. It was great the first few years but it really deteriorated recently.

We can actually drop one of Ubuntu or Travis as both are testing the same stuff.

Let's drop Travis in a month or two, when we're sure everything is working properly.

It's nice to have the redundancy (especially since it runs in parallel).
