We've replaced the normal AmFilter with one that doesn't proxy under ws/*, looking into is
code

sorry I don't understand what you are saying here? You are saying your application has?  If
it doesn't proxy it doesn't really follow yarn security rules?

You are correct that the YarnConfiguration is public, but the getProxyHostAndPort and now
getProxyHostsAndPortsForAmFilter handle other things for you.  https, RM HA, etc...

> ApplicationMasters are supposed to go through the ResourceManager web app proxy if they
have web UI's so they are properly secured.  There is currently no public interface for Application
Masters to conveniently get the proxy host and port.  There is a function in WebAppUtils,
but that class is private.  
> We should provide this as a utility since any properly written AM will need to do this.
