Make BASE_URL_FORMAT, MANAGEMENT_API_AUD_FORMAT configurable

[Ikana]

We are using istio as our service mesh, and we need to change the protocol of the api endpoint to http so that the communication from the service to the mesh is over http and then https over the internet.

Can you explain your use case? I don't know what istio is or how it interacts with auth0 in any way. If you're using the SDK, you should talk with our endpoints directly.

This images describes the use case https://istio.io/blog/2018/img/https_from_the_app.svg

So you're adding a MITM between your app and Auth0?

[Ikana]

Basically yes, to log all requests the service makes on prometheus server.

I could do the change myself, but i wanted to know what the maintainers though

I discussed this internally and we decided adding support to override this, specially to add a MITM, is not something we're interested in. Thanks for asking first!
