All 2layer varnish instances are currently configured as follows:
frontend instance: name: "frontend" port: 80 admin_port: 6082 backend instance: name: "" (default) port: 3128 admin_port: 6083
For several related reasons, we'd like these to be unique per-cluster-type and per-instance-type. The listening port is particularly problematic in that it will require several interrelated changes over time, so it will be set to listen on both old and new ports for a transition period that could last a while.
The new instance names will all be non-default for the backends, and include the cluster name as a prefix, as in "text-frontend" and "text-backend".
