* lazy_property is deprecated
* Since https://github.com/odoo/odoo/commit/cea66be976c6d0746a972da8a16b7a239d12a462, Session
must be used as a dictionary when setting custom values
* Session default lifetime is now defined in odoo.http, so we can just reuse that
* Handle new session rotation logic (sessions must be findable by the first 42 chars of they key)
* Handle new session key generation for rotation (keys must be longer than 42 chars to handle devices)
``session_redis`` is not compatible with ``auth_session_timeout``.
``session_redis`` overrides property ``odoo.http.Application.session_store`` by returning a ``RedisSessionStore`` object instead of a ``odoo.http.FilesystemSessionStore`` object.
``auth_session_timeout`` expects ``odoo.http.Application.session_store`` object to define method ``get_session_filename()``, which does not exist for ``RedisSessionStore`` objects.
This results in an ``AttributeError`` that prevents user authentication, and Odoo becomes inaccessible.
