-----------------------------------
Not only am ui, but also application web ui need this.
Many applications have their own web. The web ports are allocated by slider.
The cluster nodes may only have a range of port opened through firewall. We can
assign a range of ports for WEB_PORTS, and application could use
HOST_ALLOCATED_WEB_PORT to get a web port.
> Have Slider AppMaster listen on a port from a reserved list

> The cluster nodes may only have a range of port opened through firewall. For
> the AM UI to be accessible the port used by AM UI should be within the range.
> Perhaps YARN can hand off the port to the AppMaster to listen on.
> Alternatively, application can specify a range of ports and AM uses one of
> these ports to listen on.
