MAPREDUCE-7435. Manifest Committer OOM on abfs (#5519)
This modifies the manifest committer so that the list of files
to rename is passed between stages as a file of
writeable entries on the local filesystem.

The map of directories to create is still passed in memory;
this map is built across all tasks, so even if many tasks
created files, if they all write into the same set of directories
the memory needed is O(directories) with the
task count not a factor.

The _SUCCESS file reports on heap size through gauges.
This should give a warning if there are problems.
