📄 Description

Hello, this PR makes it possible to shuffle DNS NameServers to avoid overloads to the first configured ones.

Edit: it makes sense to default shuffle_dns_servers to true, it greatly improves performance in all kinds of tasks. For comparison:

A lookup for 11500 hosts, having 1000 resolvers, and using 100 threads takes ~10 minutes to complete, with this change it only takes 55 seconds. That means ~10x of performance increase.
