[ci skip] Manage CoreDNS Corefile in Terraform and block junk NxDomain queries ...

Add kubernetes_config_map for CoreDNS to the technitium module, with a
template block for cluster.local.viktorbarzin.lan that returns NXDOMAIN
immediately. This prevents ndots:5 search domain expansion from flooding
Technitium with ~66k/day junk queries (e.g.
redis.redis.svc.cluster.local.viktorbarzin.lan).

Also enabled saveCache on Technitium so the DNS cache persists across
pod restarts.
