ingress-nginx-app release v2.0.0

Changed

Note: This upgrade is only a breaking change in the unlikely event that you have been specifying services as externalName with your Ingress as a backend. Otherwise, it is not a breaking change.

• Update controller container image to v0.48.1. (#211). This release contains several performance improvements related to the admission webhook.
• Potentially Breaking: Define --disable-svc-external-name flag by default to disable forwarding traffic to ExternalName Services. If you require this feature, you can enable forwarding again through setting controller.disableExternalNameForwarding: false in user values. (#211)
