> A new server has been added to yarn. It is a web proxy that sits in front of the AM web
UI. The server is controlled by the yarn.web-proxy.address config. If that config is set,
and it points to an address that is different then the RM web interface then a separate proxy
server needs to be launched.
> This can be done by running
> yarn-daemon.sh start proxyserver
> If a separate proxy server is needed other configs also may need to be set, if security
is enabled. 
> yarn.web-proxy.principal 
> yarn.web-proxy.keytab
> The proxy server is stateless and should be able to support a VIP or other load balancing
sitting in front of multiple instances of this server.
