yuvipanda 9bf4a64826 Dynamically set authenticator properties from YAML
We don't wanna explicitly map keys from the YAML to traitlet
config for the authentication - that's a lot of busywork for no
gain. We instead switch to using snake_case everywhere, and
dynamically set traitlet config from YAML config!
