Takes a dictionary sent by the client in the login / registration
protocol and handles the login flow.
As a side effect, this function fills in the 'creds' key on the user's
session with a map, which maps each auth-type (str) to the relevant
identity authenticated by that auth-type (mostly str, but for captcha, bool).
Args:
flows: list of list of stages
authdict: The dictionary from the client root level, not the
'auth' key: this method prompts for auth if none is sent.
flows (list): A list of login flows. Each flow is an ordered list of
strings representing auth-types. At least one full
flow must be completed in order for auth to be successful.
clientdict: The dictionary from the client root level, not the
'auth' key: this method prompts for auth if none is sent.
clientip (str): The IP address of the client.
Returns:
A tuple of authed, dict, dict where authed is true if the client
A tuple of (authed, dict, dict) where authed is true if the client
has successfully completed an auth flow. If it is true, the first
dict contains the authenticated credentials of each stage.
