Templatize the running service port

[kmasiello]

If one wants to run the Workbench/Connect/Package Manager service on a configured port (service.targetPort) it is also required to modify the configured port in multiple other locations, e.g., the port the product is listening on, and the HTTP probes.

Consider flowing the service.targetPort down through the config to ensure this is consistent and less prone to mistakes if a find/replace of the default port overlooks an entry.

@kmasiello it looks like this has been completed for all 3 products, can we close this now?

Excellent! Yes. Closing issue.
