service.beta.kubernetes.io/do-loadbalancer-hostname: Use nip.io for easier setup?

[simonhammes]

Hi,

would it be possible to automatically set the hostname annotation to ${IP}.nip.io when provisioning a loadbalancer that uses the proxy protocol?

This would make it much easier since it would essentially eliminate the need to edit the initial deployment/manually override the annotations on the ingress controller (in case it would be the only override).

The OpenStack CCM does a similar thing: kubernetes/cloud-provider-openstack#1449

This was also proposed by @regnerisch in #291 (comment)

Or, as a different approach: Support kubernetes/enhancements#1860 even though it's still in beta?

I believe this has already been implemented in other CCMs (e.g. here).

Thank you!
