Sniffing uses bound_address instead of publish_address

[GennadyAndreev]

Elasticsearch.Net version: 5.0.0-rc4
Elasticsearch version: 5.0.1

I have Elasticsearch server bound on both loopback interface and LAN interface:
network.host: ["_local_", "_site_"]

Here is part of /_nodes response:

"http": {
    "bound_address": [
        "[::1]:9200",
        "127.0.0.1:9200",
        "10.9.0.129:9200"
    ],
    "publish_address": "10.9.0.129:9200",
    "max_content_length_in_bytes": 104857600
}

SniffResponse class uses the first value of bound_address array. As a result, when I use SniffingConnectionPool, it is initialized with server [::1]:9200, and all subsequent requests go to local machine. If I use only _site_ binding, the client connects to the server normally.
