Server adapter: provide ability to link pods/'deployment config'/'replication controller'(?) when no service is available

When some OpenShift applications are not providing any services. the Eclipse OpenShift Tooling is not able to create an OpenShift server adapters to deploy new version of the application.

The only that we are sure that will be always available are pods so it would be nice to provide some fallback logic that asks you to choose a pod or uses the only one it finds​ when there is no service provided.
