External DNS PiHole

Disclaimer: This application is in alpha and is just for home-lab / playing around with.

This application is similar to external-dns in functionality, with support for PiHole application using the DNS server ability.

The application will listen to ingress events in the kubernetes cluster and will send requests to create new DNS records using another application called pihole-dns-updater. Furthermore, the application will periodically search for DNS records that exists in PiHole but dont exists in kubernetes and will remove them from PiHole if a condition is applied (Same domain with same endpoint IP address).
