Deploy OpenShift YAML manifests

[kevchu3]

I am requesting support to deploy OpenShift YAML manifests in Azure DevOps pipelines with this VSTS plugin.

Background:
Azure DevOps pipelines has a number of supported out-of-the-box tasks, of which one of them is "Deploy to Kubernetes". This does a great job with applying Kubernetes manifests with kubectl. This OpenShift plugin has no such feature, and the oc commands that we can perform with the plugin are mostly limited to command line that don't take file inputs. In a GitOps world, this is quite limiting as one would expect that YAML manifests (i.e. a deployment) would be checked into Git and applied as part of the pipeline. The Kubernetes plugin is also not a perfect fit for deploying to OpenShift as it can only manage Kubernetes resources, not OpenShift ones. Thus, I'd like to request the ability to deploy OpenShift YAML manifests as a feature.
