Move from Travis to GitHub Actions

[jjhursey]

• Due to rate limiting restrictions in Travis, move to GitHub Actions

To see what this looks like click on the Checks tab in the PR below:

• playing with GH Actions jjhursey/pmix-standard#2

Apparently, GitHub made an agreement with DockerHub that avoids the rate limit issue. Even if they hadn't we could add an authentication token to the Action to work around it. So far this looks like it is working.

Thanks @jjhursey for putting this together! Good to know that Github Actions are exempt from docker hub pulls.

I went ahead and created the pmix organization on docker hub (and added you @jjhursey as an owner) if we eventually want to switch to that top-level namespace:

Suggested change

	run: docker run --rm -v ${GITHUB_WORKSPACE}:/home/pmixer/pmix-standard jjhursey/pmix-standard /bin/bash -c "cp -R /home/pmixer/pmix-standard pmix-build && cd pmix-build && make"
	run: docker run --rm -v ${GITHUB_WORKSPACE}:/home/pmixer/pmix-standard pmix/pmix-standard /bin/bash -c "cp -R /home/pmixer/pmix-standard pmix-build && cd pmix-build && make"

Thanks for setting that up. I was thinking of moving those github repos into the pmix or openpmix GitHub namespace anyway, so it would make sense to rename the container namespace at the same time. I'll put that on my near-ish term todo list. We can make this change once that is moved over.

@SteVwonder can you give a final review so we can merge?
I'll work on moving those containers in the next few weeks. We can update the GH Action once that's done.

LGTM!
