Use real identity provider locally

**Is your feature request related to a problem? Please describe.**
When developing locally, I cannot test my application against a real identity provider using the static web apps CLI.

**Describe the solution you'd like**
I would like to have the option to use the mock authentication interface or a real provider.

**context**
I want to be able to turn off this interface and use auth0 locally.
