Evaluate how https://github.com/hellofresh/janus can help building a minimal service proxy with routing capabilities.
Eg:
The service should also provide the usual /api/status and /api/metrics endpoints.
The routing should be configured in a yaml/json file can be deployed/managed with a ConfigMap on OpenShift.
The service can be bootstrapped using https://github.com/fabric8-services/fabric8-starter to reuse some packages from https://github.com/fabric8-services/fabric8-common, but here, Goa may not be needed (the /api/status endpoint could be handled with a simpler net/http handler)
