Command-line option to disable automatic PORT assignment

[canadaduane]

We have an app that assigns its own PORT values for each of the services. Is there a way to tell node-foreman NOT to assign a value to the PORT env var?

Clearly there is a way to explicitly set the PORT env var, and node-foreman will respect it; however, in our case our apps/services also respect the PORT value and don't fall back to their expected default values when PORT is set.
