remove hard coded port 8080 for routes, services and deployment configs

[lholmquist]

currently, nodeshift will hard code port 8080 for the "port" or "targetPort" for the routes, services, deploymentConfigs, health check(enricher)

We probably should not be hard coding these, but making them just the default.

I originally thought that a PORT=.... env var should change this, but i'm not entirely sure. I'm thinking more of a flag --deploy.port or similar.

I think the flag makes more sense here, since it is a value for something nodeshift is going to create, not how nodeshift should run.
