Fix defaults for apiserver_loadbalancer_domain_name

Browse Source 
Since we're not longer injecting pseudo DNS into /etc/hosts,
'lb-apiserver.kubernetes.local' (the previous default) won't resolve to
anything.

Instead, default to the loadbalancer IP if defined, or to the node local
loadbalancer if it's in use.

Make the necessary adjustements in use site to deal with ip addresses as
well as hostnames.
