dns: add caches for server
There are two type of answer: local and non-local.
Local answer is a DNS record that is loaded from hosts file or master
zone file.
Non-local answer is a DNS record that is received from parent name
servers.
Server caches the DNS answers in two storages: map and list.
The map caches store local and non local answers, using domain name as a
key and list of answers as value,
domain-name -> [{A,IN,...},{AAAA,IN,...}]
The list caches store non-local answers, ordered by last accessed time,
it is used to prune least frequently accessed answers.
Local caches will never get pruned.
