Multi-arch images with Github Actions

[awilmore]

Hi @lwolf,

I've created two Github actions that should do the job of replacing Travis:

• test.yml : runs on pull request creation and simply runs make test at this stage
• release.yml : runs on tag creation, and uses GoReleaser to build and push multi-arch images and manifests

Caveat - this is my first time using GoReleaser. I tested this using my dockerhub login and it seems to work okay: https://hub.docker.com/r/awilmore/kube-cleanup-operator/tags

The github action requires that you set the values for QUAY_USERNAME and QUAY_PASSWORD as action secrets here: https://github.com/lwolf/kube-cleanup-operator/settings/secrets/actions

That's about it. I hope this is enough info to get this set up as your Travis replacement.

UPDATE

This PR addresses:

• Replace travis-ci with github-actions #65
• add multiarch docker build #21

thanks. looks good. let's try it...

[lwolf]

it did work, but there are a couple of things:

1. the resulting image was tagges as quay.io/lwolf/kube-cleanup-operator:0.8.4 (should be v0.8.4). I'll update .goreleaser to prepend v` before the {{version}}

The other thing is that goreleased haven't added the images to the release description (but to be honest I don't remember if it ever did that or I was adding it manually all the time).

Anyway thanks again!
