Set port via env variable

[JosiahParry]

I am writing a script that will launch a genie app on a random port that is discovered at run time. Say that port is 8310, how can we ensure that Genie.jl uses it without using

using Genie, Logging

Genie.Configuration.config!()

as shown at https://learn.genieframework.com/framework/genie.jl/docs/configuration

@JosiahParry Not sure what you want to achieve. You can pass the port as part of the ENV when the app starts, or you can set it in the app using the available API. Logically I can't think of any other ways to do it. Can you explain the reasoning behind your situation?

If you can use the ENV, just set the PORT var
