Button to create new project on Openshift/Kubernetes

Description

When preparing the idea-to-production demo, there's a manual step to create a project in Openshift to house the application. This can be programmatically done in a build script, but since it's only a one-time action, it's not something that you'd think needs to be scripted for each project. We should consider adding a web UI to create a matching Openshift project for a GitLab project.

Proposal

• On some project page, add a button to create a project on Openshift/Kubernetes.
• Either enforce that the project names are the same, or store the new Openshift project name for the GitLab project and make it available as a variable for CI/CD.
