The new API extension ``extraroute-atomic`` introduces two new member
actions on routers to add/remove routes atomically on the server side.
The use of these new member actions
(``PUT /v2.0/routers/ROUTER-ID/add_extraroutes`` and
``PUT /v2.0/routers/ROUTER-ID/remove_extraroutes``) is always preferred
to the old way (``PUT /v2.0/routers/ROUTER-ID``) when multiple clients
edit the extra routes of a router since the old way is prone to race
conditions between concurrent clients and therefore to possible lost
updates.
