Specify an Authentication Endpoint

[bbengfort]

Scope of changes

Allows users to specify an auth url to authenticate with Quarterdeck rather than relying on the Endeavor proxy. This is a temporary fix for the 503 proxy issue in Endeavor but will also mean that we can directly access Quarterdeck methods (e.g. for users and api keys) in the future, so it's an important addition.
