Motivation: We should not try to use UnixResolverDnsServerAddressStreamProvider when on Windows as it will log some error that will produce noise and may confuse users. Modifications: Just use DefaultDnsServerAddressStreamProvider if windows is used. Result: Less noise in the logs. This was reported in vert.x: https://github.com/eclipse/vert.x/issues/2204
