Description:
Today by default, Envoy Gateway watches for resources (Gateways, HTTPRoutes) in all namespaces, and deploys managed resources (Envoy Deployment, Service) in a single namespace (where EG is running e.g. envoy-gateway-system)
It would be great if the project supported other modes such as

• watch for resources in a single namespace and/or

• API feat: add API for Deployment Mode #1413
• Implement Implement Watch Namespaces #1610
• Docs

• deploy in multiple namespaces (where Gateway is created)

• API
• Implement
• Docs

This intent could be defined in the EnvoyGateway config
