How to set grpc.dns_enable_srv_queries=1?

[niuzheng168]

We are migrating our project to grpc.net, what's the right way to set grpc.dns_enable_srv_queries=1?

Channel channel = new Channel("dns://127.0.0.1:8010/test.my-company.com", ChannelCredentials.Insecure, new[]
  {
    new ChannelOption("grpc.lb_policy_name", "grpclb"),
    new ChannelOption("grpc.service_config", "{\"serviceConfig\":{\"load_balancing_config\":{ \"grpclb\": {} },\"waitForReady\":true}}"),
    new ChannelOption("grpc.dns_enable_srv_queries", 1)
  });

I don't believe we can support that setting at the moment. The built-in DNS functionality in .NET - https://docs.microsoft.com/en-us/dotnet/api/system.net.dns.gethostaddressesasync?view=net-6.0 - only supports querying A records.
