Move TRSS to OpenShift

[aahlenst]

In light of #1679, we should investigate moving TRSS to OpenShift which is our main platform for production applications. It already runs the API and jlink.online. Currently, TRSS is hosted on a EC2 machine at AWS in an ad-hoc fashion.

• Investigate whether TRSS can be run on OpenShift. If not, initiate the necessary adjustments.
• Ensure TRSS provides endpoints for health checks (indicate whether TRSS is up, MongoDB is operational).
• Codify the deployment of OpenShift (Dockerfile, Ansible, ...).
• Create staging environment.
• Work out backup strategy and implement it.
• Create production environment.
• Monitor SSL certificate, reachability, health endpoints and resources of TRSS.

Thanks @aahlenst Does OpenShift provide any backup support? Or is there any server we can use to back up the data?

Haven't seen a "backup now" button but I'm sure we'll find a solution.
