Test for OpenShift 4.x+ compatibility

[poikilotherm]

There had been previous approaches to use OpenShift with Dataverse.
Since OS4 is based on Kubernetes 1.16, we should be able to use our tools with it.

OS is a very popular K8s distribution, so it would spread the usability and adaption further. It has many neat features like built-in Jenkins, registry etc. It might be useful for local dev, too.

Sounds great. Just to chime in, Adam Bien talks about OpenShift all the time on his airhacks podcast. It does seem to be popular and supporting it better might help adoption (strategic goal number 1 for Dataverse). Plus, it would make our contacts at Red Hat happy. I forget if I told you that we're talking (off and on) about getting Dataverse in OpenShift catalog some day. It would be great advertising. 😄 Please remind me to tell you more about this.

We have an OpenShift cluster in DataverseEU project and going to try Kubernetes installation there. I'm not expecting too much differences, usually it's only Storage specification should be changed to get it there.
