Capsule CoreDNS Plugin

[oliverbaehler]

Describe the feature

Currently by default it's possible to resolve any pod/svc from any pod. We would like to provide a custom CoreDNS plugin which allows the following:

• DNS Resolution only within Tenant or single namespace
• Whitelisting of namespaces (eg. default for kubernetes.default.svc

The plugin should be chained with the kubernetes plugin and leverage the provided labels/metadata per request.
