docs: Execute the delete on HBase, invoking the deleteModifier before executing
  the delete if deleteModifier is not null.
  
  Any DeleteActionModifers registered with registerDeleteModifier will be
  invoked after the deleteActionModifier passed to this method is invoked,
  and before the Delete is executed.
  
  @param deleteAction
  The Delete to execute.
  @param deleteActionModifier
  Invoked before the Delete to give callers a chance to modify the
  Delete before it is executed.
  @return True if the delete succeeded, False if the put failed due to update
