Handling Non-Standard OAuth2 Implementations

[yokonsan]

Environment

Flask-Appbuilder version: 4.4.1

Describe the expected results

If a third party's OAuth2 implementation does not comply with standards, such as using app_id instead of client_id for the redirection parameter, and the access_token field also deviates from the norm, is there a mature solution available?

If your provider is a one that could be used by other people/organisations than i would suggest to create a pull request where you add a provider in the flask_appbuilder/security/manager.py file under the get_oauth_user_info() method.

If you are using a custom provider that is used only by you the cleanest solution would be to extend the security manager and use that when you initialise the app.

Thank you. I've rewritten the OAuth2 related methods of the Authlib library and recompiled it.
