we use FQDN as inventory_hostname

Define apiserver flags directly instead of relying on auditPolicy section in order to have the ability to redirect audit log to stdout with kubeadm

Hostname must be a valid DNS name, which is checked as https://github.com/kubernetes/apimachinery/blob/master/pkg/util/validation/validation.go#L115

The situation I have encountered is that my hostname contained underscore which is disallowed and apiserver refused to start.
