Currently, the Session proto id_token field is populated with Pomerium
session data during initial login, but with IdP ID token data after an
IdP session refresh.
Instead, store only IdP ID token data in this field.
Update the existing SetRawIDToken method to populate the structured data
fields based on the contents of the raw ID token. Remove the other code
that sets these fields (in the authenticateflow package and in
manager.sessionUnmarshaler).
Add a test for the identity manager, exercising the combined effect of
session claims unmarshaling and SetRawIDToken(), to verify that the
combined behavior is preserved unchanged.
Consolidate all logic specific to the stateless authenticate flow into a
a new Stateless type in a new package internal/authenticateflow. This is
in preparation for adding a new Stateful type implementing the older
stateful authenticate flow (from Pomerium v0.20 and previous).
This change is intended as a pure refactoring of existing logic, with no
changes in functionality.
