Sets a custom expiration for the session. ``value`` can be an integer,
a Python ``datetime`` or ``timedelta`` object or ``None``.
If ``value`` is an integer, the session will expire after that many
seconds of inactivity. If set to ``0`` then the session will expire on
browser close.
If ``value`` is a ``datetime`` or ``timedelta`` object, the session
will expire at that specific future time.
If ``value`` is ``None``, the session uses the global session expiry
policy.

Returns ``True`` if the session is set to expire when the browser
closes, and ``False`` if there's an expiry date. Use
``get_expiry_date()`` or ``get_expiry_age()`` to find the actual expiry
date/age, if there is one.

is created (otherwise a CreateError exception is raised). Otherwise,

If this operation isn't possible on a given backend, it should raise
NotImplementedError. If it isn't necessary, because the backend has
a built-in expiration mechanism, it should be a no-op.
