Using `Sidecar` import

The egress.hosts field in Sidecar allows specifying a list of configurations to import. Only configurations matching the specified criteria will be seen by sidecars impacted by the Sidecar resource.

For example:

apiVersion: networking.istio.io/v1
kind: Sidecar
metadata:
  name: default
spec:
  egress:
  - hosts:
    - "./*" # Import all configuration from our own namespace
    - "bookinfo/*" # Import all configuration from the bookinfo namespace
    - "external-services/example.com" # Import only 'example.com' from the external-services namespace
