> So far RM, MR AM, DA AM added/changed new config to enable the feature to 
> write the timeline data to v2 server. It's good to have a YARN 
> timeline-service.version config like timeline-service.enable to indicate the 
> version of the running timeline service with the given YARN cluster. It's 
> beneficial for users to more smoothly move from v1 to v2, as they don't need 
> to change the existing config, but switch this config from v1 to v2. And each 
> framework doesn't need to have their own v1/v2 config.
