Disable Dangerous Downtime-causing Default

According to https://docs.digitalocean.com/products/kubernetes/how-to/configure-load-balancers/#ssl-certificates

you can specify whether to disable automatic DNS record
creation for the certificate upon the load balancer’s creation using the
do-loadbalancer-disable-lets-encrypt-dns-records annotation. If you
specify true, we will not automatically create a DNS A record at the
apex of your domain to support the SSL certificate.
