Javalin: Replace Travis with GitHub actions ?

Found this repository with GitHub actions for Maven after a quick search. Might have to create something ourselves to use the Maven wrapper we have here in the Javalin repository.

Edit: This example seems more up to date: https://github.com/actions/starter-workflows/blob/master/ci/maven.yml

Seems they switched to YAML for the GitHub action files. https://help.github.com/en/articles/migrating-github-actions-from-hcl-syntax-to-yaml-syntax

We can cover testing with multiple JDKs by using matrix testing: https://github.com/actions/setup-java#usage, although we need to make sure Maven uses the specified JDK then.

Thanks a lot for looking into this @Playacem. Are you able to make a pull request for an action setup?

[Playacem]

Sadly I am not in the GitHub actions beta yet, so I can't make a pull request. Will do a pull request when I have access and some time next week.

Great, looking forward to it!
