MAHOUT-1493: Add CLI options for --overwrite and --alphaI to NB Drivers
Presently `mahout spark-trainnb` will not complete if a model already
exists in the output directory. These last options add in an `--overwrite`
option to overwrite a model in the given output directory.
as well:
- add `.par(auto = true)` to the input Drm
- ads a `delete(...)` method to `Hadppo1HDFSUtils` which does not handle
any IO exceptions
- adds an almost trivial `--alphaI` option to set the Laplace smoothing
factor from the CLI
This patch will complete the full port of the old MapReduce Naive Bayes to
the `math-scala` and `spark` modules.
