Enable non API-key auth mecanism #48
Description
It might be convinient to allow authentication mecanisms other than "api key". E.g. for people using heroku's cli tool, taking advantage of the requests library ability to read .netrc files (as noted here) could be nice.
Several issues prevent that:
- API assumes user will use an API Key and nothing else.
- Even if passing a custom requests.Session (as allowed by the API), code will override some of the session settings, rendering ability to pass a custom session quite pointless.
