Some of the app engine console was updated.
Instead of setting a "default" version, it now uses traffic splitting. So
your live version is the default, as it gets 100% of the traffic.
I also believe you cannot dispatch to specific module versions.
Dispatch.yaml only allows routing to a module (the version is then
determined by the traffic splitting)
NB - if you had two separate modules, you would need to use a dispatch.yaml
to assign the custom domains, it is not done automatically.
