The podman documentation site uses javascript to display
API documentation at:
http://docs.podman.io/en/latest/Reference.html
As input, the javascript sources from a CORS-enabled Google Cloud
Storage object. This commit ensures the storage object is present and
updated for every Cirrus-CI execution context: Tags, Branches, and PRs.
As of this commit, the documentation site only utilizes the object
uploaded by the Cirrus-CI run on the `master` branch:
`swagger-master.yaml`. The file produced and uploaded due to a PR is
intended for testing purposes: Confirm it's generation and uploading are
both functional.
