MAPREDUCE-7403. manifest-committer dynamic partitioning support. (#4728)
Declares its compatibility with Spark's dynamic
output partitioning by having the stream capability
"mapreduce.job.committer.dynamic.partitioning"

Requires a Spark release with SPARK-40034, which
does the probing before deciding whether to 
accept/rejecting instantiation with
dynamic partition overwrite set

This feature can be declared as supported by
any other PathOutputCommitter implementations
whose algorithm and destination filesystem
are compatible.

None of the S3A committers are compatible.

The classic FileOutputCommitter is, but it
does not declare itself as such out of our fear
of changing that code. The Spark-side code
will automatically infer compatibility if
the created committer is of that class or
a subclass.
