Kubernetes default format should be reversed

79ecffb#diff-6bcfd5e9b288faaba5215a75e1c4dfa5R22 should be reverted.

i agree that the most specific part should be on the left, but that only applies if there's a dot between the components., e.g. postgres.teamname.svc.cluster.local

if we concatenate two components via a dash this doesn't apply, e.g. teamname-postgres.app.example.org.
