Change auth tests to include all shields of the base class.
The code is formated to be used in more general cases and increases code reuseability.

We already test all existing classes, no need for a dummy

Add getBadgeExampleCall to extract the first OpenAPI example then reformat it for service invoke function.

Add the testAuth function which tests auth of a service (badge) using a provided dummy response.

Add all auth methods used to testAuth to be generic and used by all services.
Add helper functions to make testAuth more readable

Use apiHeaderKey & bearerHeaderKey as function params rather then extracting them with regex from function strings.

Those options are now part of an options object param joined with the contentType that replaces header.

header was originaly added for setting content type of the reply, so it makes more sense to directly set the content type

Before this commit the QueryStringAuth would only work for the key of stackexchange.
This commit makes the testAuth function generic and allows passing user and pass keys.

Might set wrong header for jwt login request.
This commit fixes that.

Some services might have more then one authOrigin.
This commit makes sure we test for redundent authOrigins as well as support requests to them if needed.

Prior to this change, JwtAuth testing would lead to erros due to the absence of a specified login endpoint,
Nock would be dumplicated for both login and non login hosts and indicate a missing request.

This commit enforces the requirement for a new jwtLoginEndpoint argument when testing JwtAuth.
The argument seperates the endpoint nock scope from the behavior of the request nock.
