Note: Before merging, we need to make sure that new Envoy binaries are up in https://download.konghq.com/mesh-alpine/

Envoy broke DNS filter compatibility between 1.18 and 1.19. Not sure how we are going to be able to upgrade past this. IIUC, we can't require a big-bang conversion to Envoy 1.19.

How do we do that?

[jpeach]

Abandoning the 1.19.1 upgrade. Hopefully we will be able to upgrade to 1.19.2 if the upstream protobuf changes work out.
