Use Fedora CoreOS image streams on Google Cloud

Browse Source 
* Add `os_stream` variable to set a Fedora CoreOS stream
to `stable` (default), `testing`, or `next`
* Deprecate `os_image` variable. Remove docs about uploading
Fedora CoreOS images manually, this is no longer needed
* https://docs.fedoraproject.org/en-US/fedora-coreos/update-streams/

!!! tip
Regions are listed in [docs](https://cloud.google.com/compute/docs/regions-zones/regions-zones) or with `gcloud compute regions list`. A project may contain multiple clusters across different regions.
## Fedora CoreOS Images
Fedora CoreOS publishes images for Google Cloud, but does not yet upload them. Google Cloud allows [custom boot images](https://cloud.google.com/compute/docs/images/import-existing-image) to be uploaded to a bucket and imported into your project.
[Download](https://getfedora.org/coreos/download/) a Fedora CoreOS GCP gzipped tarball and upload it to a Google Cloud storage bucket.
```
gsutil list
gsutil cp fedora-coreos-31.20200323.3.2-gcp.x86_64.tar.gz gs://BUCKET
```
Create a Compute Engine image from the file.
```
gcloud compute images create fedora-coreos-31-20200323-3-2 --source-uri gs://BUCKET/fedora-coreos-31.20200323.3.2-gcp.x86_64.tar.gz
```
Set the [os_image](#variables) in the next step.
## Cluster
Define a Kubernetes cluster using the module `google-cloud/fedora-coreos/kubernetes`.
