Alexey Kachayev c0ae5e697c DnsAddressResolverGroup to use pluggable DnsNameResolverBuilder (#7793) ... Motivation: Right now to customize DNS name resolver when using DnsAddressResolverGroup one should subclass implementation and override newNameResolver method when in fact it's possible to collect all settings in a DnsNameResolverBuilder instance. Described in #7749. Modifications: - Added new constructor for DnsNameResolverBuilder in order to delay EventLoop specification - Added copy() method to DnsNameResolverBuilder to provide an immutable copy of the builder - Added new single-argument constructor for DnsAddressResolverGroup and RoundRobinDnsAddressResolverGroup accepting DnsNameResolverBuilder instance - DnsAddressResolverGroup to build a new resolver using DnsNameResolverBuilder given instead of creating a new one - Test cases to check that changing channelFactory after the builder was passed to create a DnsNameResolverGroup would not propagate to the name resolver Result: Much easier to customize DNS settings w/o subclassing DnsAddressResolverGroup		2018-04-26 08:04:01 +02:00
