feat: support nameserver resolver

[xujianhai666]

use nameserver resolver instead of nameserver addr, we can pass
passThrough for direct addr, httpResolver for domain, envResovler
for env param.

Closes #455

IMO, it is better to add a new nameserver resolver, but for old users, it is better to keep the "WithNameServer" at the same time and do create a default resolver inner for it.
