   ### Description of PR
   
   (rebased and reopened due to being auto close some time back)
   
   DatanodeManager can changes heartbeatRecheckInterval via reconf API but 
HeartbeatManager's copy of heartbeatRecheckInterval is fixed at initialization 
and won't update when DatanodeManager updates with a new config.
