Convert CI from Travis to Github Actions

[godber]

We need to convert the ES asset CI to Github Actions, the tests currently iterate over opensearch versions and aren't as easy as the other assets (e.g. it's not just yarn test:all). So we will only re-use the shared build/publish workflow and implement a custom test workflow for the time being.

This will probably address the need for a Node 18 build as well:

I got this partly working:

https://github.com/terascope/elasticsearch-assets/actions/runs/5216071478/jobs/9414485604

I had to disable the node 18 tests in some case, I'll come back and retry those. Also the tests linked to above failed initially and I had to retry about half of them. So it's only "kind of" working at this point.

A question I have for @jsnoble is what can we do to disable the Opensearch instance from starting all of the time. Ideally it would only run in the cases where it is needed.

Most of this has been completed and merged to master here:

#1003

I have the following concerns or TODOs:

• we should test builds after tests complete
• add MacOS test back
• The Opensearch container startup timeouts are still a known retriable failure that I haven't gotten to the bottom of.

This is sufficiently done
