> The relative speed of EC recovery comparing to 3x replica recovery is a function of (EC
codec, number of sources, NIC speed, and CPU speed, and etc). 
> Currently the EC recovery has a fixed {{xmitsInProgress}} of {{max(# of sources, # of
targets)}} comparing to {{1}} for 3x replica recovery, and NN uses {{xmitsInProgress}} to
decide how much recovery tasks to schedule to the DataNode this we can add a coefficient for
user to tune the weight of EC recovery tasks.
