Configure DNS record TTL (Time-To-Live)

An optional annotation external-dns.alpha.kubernetes.io/ttl is available to customize the TTL value of a DNS record.

To configure it, simply annotate a service/ingress, e.g.:

apiVersion: v1
kind: Service
metadata:
  annotations:
    external-dns.alpha.kubernetes.io/hostname: nginx.external-dns-test.my-org.com.
    external-dns.alpha.kubernetes.io/ttl: "60"
  ...

TTL must be a positive integer encoded as string.
