Review comment:
       This description is somewhat incorrect. This config adds different 
random suffix for different reporter instances, but it is not necessary that 
each task manager has its own metrics reporter (although for most of the time 
it is the case). For example a mini cluster only has one metrics reporter (see 
`MiniCluster#start`).
