MINOR: dns: implement a LRU cache for DNS resolutions Introduction of a DNS response LRU cache in HAProxy. When a positive response is received from a DNS server, HAProxy stores it in the struct resolution and then also populates a LRU cache with the response. For now, the key in the cache is a XXHASH64 of the hostname in the domain name format concatened to the query type in string format.
