[MAPREDUCE-4932] mapreduce.job#getTaskCompletionEvents incompatible with Hadoop 1

Description

In MR1, org.apache.hadoop.mapreduce.Job#getTaskCompletionEvents takes one argument: int startFrom. In MR2, it now takes an additional argument: int numEvents (which is the max number of events to get). This makes them incompatible.

I propose we add a second getTaskCompletionEvents method that simply calls the other one with numEvents set to Integer.MAX_VALUE to replicate the behavior of the MR1 version.
