> As part of YARN-3895 ,  the timeline collector will enable storing the domain information
in denormalized in the tables when security is enabled. 
> The collector would need to maintain a map in memory for app id to domain id & info
and append this to entities while writing. 
> In case the collector goes down, this map is to be repopulated which is part of YARN-8089
