Remove openshift/api package and code references to Routes
Summary
Removes the openshift/api package and references in code to Routes, which were not used.
These are left over from the inherited codebase, where Routes were created directly. We no longer do that, instead using OpenShift's ability to create Routes from Ingress definitions. This is further documented in !451 (merged).
Closes #671 (closed).
