Add github actions for test and release

Everytime we want to release a new version of kubernetes-event-exporter, we need to build
the binaries to be deployed. This change updates the existing GitHub actions to use
https://goreleaser.com/ci/actions/ to build/test when code is pushed or a PR is created
and create a release with binaries when a new tag is pushed.
