ARROW-1618: Reduce Heap Usage (Phase 1)
cc @jacques-n , @icexelloss , @BryanCutler
This is initial small phase of our attempt to reduce heap usage per vector.
As part of investigation, we are better off addressing few things as part
of subtasks for ARROW-1463. Accordingly, I need to update the requirements
document w.r.t heap usage for ARROW-1471.
This patch gets rid of Release Listener object in Allocation Manager as all
the logic is implemented as part of AllocationManager itself.
