Function discoverRouteSuffix

pkg/config/sync.go:211–248

discoverRouteSuffix attempts to determine a clusterHostSuffix that is compatible with the current cluster. On OpenShift, this is done by creating a temporary route and reading the auto-filled .spec.host. On Kubernetes, there's no way to determine this value automatically so ("", nil) is returned.
