> {{WebAppProxyServlet}} use {{HttpClient}} to download URL for AppMaster.
> {{HttpClient}} bind the local address according to {{yarn.web-proxy.address}}.{{HttpClient}} should use the independent address for following situation: 
> There are two network cards.{{CardA}} for user to access cluster, {{CardB}} for cluster inner communication.User can only access {{Web-Proxy}} by {{CardA}}.
> {{CardA}} can't ping {{CardB}}.
> So we have to bind {{Web-Proxy}} to {{CardA}}, and then specify {{HttpClient}} use {{CardB}}.
