Configurability in marking the auth headers as temporary

[rafiron]

In the newer versions of Postman, authentication headers come as temporary headers and don't come when you try to export them - creating collections or in the code section of the application.
More details here https://github.com/postmanlabs/postman-app-support/issues/1463

I would really like to have a configurability on this. So that when I want to use authentication headers in the request not just as a temporary header, I can use it. (The default behaviour of this can indeed be set to the one in newer versions).

There are several use cases of mine, where I want to add auth headers but I simply can't export it. Having a configuration somewhere would allow users to turn off this behaviour, if they choose to do so.
