Allow Custom Authentication type configuration for DB connection

Is your feature request related to a problem? Please describe. Current databricks connection setup allows only access token, and cannot be changed to configure other type

Describe the solution you'd like to allow authType for databrciks or any other setup, where based on organisation authentication mechanism we can configure it. in this case if I want to confugure OAuth configuration for databricks , there is no way to configure it.

Describe alternatives you've considered No alternative solution, unable to use cubejs as auth mechanism is not supported by my organisation authenticatoin mechanism of Oauth.
