How to setup contour as level 2 proxy

What question do you have?: How to setup contour as level 2 proxy

Anything else you would like to add: As described here, envoy needs some more configuration when running as level 2 proxy. -https://www.envoyproxy.io/docs/envoy/latest/configuration/best_practices/level_two

Environment:

• Contour version: v1.25.1
• Kubernetes version: (use kubectl version):
• Kubernetes installer & version:
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):

Sounds reasonable to offer the configurability of this field to allow users to run their Envoy's in line with Envoy's "L2" guidelines: https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/network/http_connection_manager/v3/http_connection_manager.proto#envoy-v3-api-field-extensions-filters-network-http-connection-manager-v3-httpconnectionmanager-stream-error-on-invalid-http-message

This would have to be a new feature, a global configuration that can be applied by an operator who knows how Contour is deployed so they can enable it correctly, probably should go here: https://projectcontour.io/docs/1.25/configuration/#listener-configuration
