ci: Move CI to GitHub Actions

[gribnoysup]

Description

This PR moves data-service CI to GitHub Actions and away from Travis. This PR doesn't try to improve the config, just copies whatever Travis CI was doing

Motivation and Context

We are consistently running out of free minutes on Travis. I'm doing this change now as I'll soon submit some changes to the lib and want the CI to work
