App Engine Flex Session Affinity

[wesoos]

Hello, I believe the app engine flex uses the cloud load balancers underneath, correct? When will we be able to configure the load balancer to use session affinity? You can do it for a normal cloud load balancer in front of compute engine instances, why not app engine?

Using the gcp-datastore-sessions variable does not work in all cases, especially Vaadin apps where session affinity is required.

There are a lot of people wanting this feature!
