Remove JDK1.7 method InetSocketAddress#getHostString since JDK1.7 is only supported by Android after 4.4 KitKat.

Now we pass the host directly into OkHttpClientTranport for 2 reasons:
1. We don't need to call InetAddress/InetSocketAddress.getHostName(), which will do a reverse DNS lookup, may return a different value other than user specified.
2. In some tests, we want to change the host to match TLS cert, in such case, we can use OkHttpChannelBuilder.overrideHostForAuthority(String host) to override the host, then the transport will get the overridden value.
