Support GitOps with an option to output as YAML

[braunsonm]

Right now in order to deploy a function you need to run func deploy on a machine that is configured with access to your Kubernetes cluster.

In a GitOps approach, func deploy would have a parameter to output the generated Knative Service CR as YAML for example func deploy --build false -o yaml > knative-service.yml. This would allow GitOps tools like ArgoCD and Flux to read this committed YAML document in the source repository.

Yes, exporting a .yaml is on our roadmap. If you don't want CI to have cluster access, you can use func build to update a container, and then define your service directly with service.yaml checked into source control
