> The NodeManager should limit the number of applications that have their logs being aggregated
in parallel.  This will reduce the load on the NN.  We need to ensure that the RM will continue
to renew the token while this is happening.  We also should look if the NM starts to fall
behind if it can delete some of the logs or not.
