[app/dns] Support per-client configuration for fakedns (#2212)
* Move `filterIP` from `hosts.go` to `dnscommon.go`

* Implement adding pools for fakedns.HolderMulti

* Implement per-client fakedns for DNS app

* Remove `dns.ClientWithIPOption` and replace with new programming model

* Implement JSON config support for new fakedns config

* Fix lint and tests

* Fix some codacy analysis
