Support header-based authentication for maven repositories (like Gitlab)

[chrisbetz]

Hi,

some repositories (in my case Gitlab) need http headers for authentication. In maven, these would be configured in settings.xml. In Gradle there's HttpHeaderAuthentication/Credentials.

I already opened an issue on pomegranate and I'm willing to support development by creating a PR. However, I'd like some input on your views on this first.

Sincerely,

Chris

Hey, sorry for the delay. If this gets added to Pomegranate then we should definitely support it from within Leiningen; happy to take a patch for that.
