Move from Travis CI to GitHub actions

Probably worth doing when possible, as per @tyvsmith's advice 😁

Is there a brief explanation anywhere of the advantages?

For my own future reference, I think resource limitations on Travis CI are a good enough reason to move. Also, switching to GitHub Actions will let us easily run tests on Windows.

Travis CI is still the better and is being used my many big organisations however i would like to work on this if you give me a go ahead cc @msridhar @lazaroclapp

Thanks for the offer, @sherrif10! But, I think it will be easier for a maintainer still at Uber like @lazaroclapp to take care of this one, as it requires dealing with permissions to set up GitHub Actions, adding credentials to set up snapshot build uploading, etc.
