Proposed title of this feature request

 The ability to use CRD source

What is the nature and description of the request?

 My customer has asked if we can consider something like this is (see attached image) what I was expecting to do external-dns/docs/sources/crd/dnsendpoint-example.yaml at master · kubernetes-sigs/external-dns · GitHub

For example:

apiVersion: externaldns.k8s.io/v1alpha1
kind: DNSEndpoint
metadata:
  name: examplednsrecord
spec:
  endpoints:
  - dnsName: foo.bar.com
    recordTTL: 180
    recordType: A
    targets:
    - 192.168.99.216
    # Provider specific configurations are set like an annotation would on other sources
    providerSpecific:
      - name: external-dns.alpha.kubernetes.io/cloudflare-proxied
        value: "true"

Why does the customer need this? (List the business requirements here)

They wish to be able to use the CRD's for configuring this operator
