Implement ns lookup allowlist (#1420)

The ns-lookup accepts domain names as well as suffixes, e.g.:

```
--allow-resolve=* # allow all domain names
--allow-resolve=example.com # only allow example.com name resolution
--allow-resolve=example.com --allow-resolve=*.example.com # allow example.com and its subdomains' name resolution
```
