Batch Predictions
JIRA issue [PIO-105](https://issues.apache.org/jira/browse/PIO-105)
Provides a new `pio batchpredict` command.
Reads from multi-object JSON input file. Example:
```json
{"user":"1"}
{"user":"2"}
{"user":"3"}
{"user":"4"}
{"user":"5"}
```
Writes to multi-object JSON output file (actually Hadoop partition files).
Example:
```json
{"query":{"user":"1"},"prediction":{"itemScores":[{"item":"1","score":33},{"item":"2","score":32}]}}
{"query":{"user":"2"},"prediction":{"itemScores":[{"item":"5","score":55},{"item":"3","score":28}]}}
{"query":{"user":"3"},"prediction":{"itemScores":[{"item":"2","score":16},{"item":"3","score":12}]}}
{"query":{"user":"4"},"prediction":{"itemScores":[{"item":"3","score":19},{"item":"1","score":18}]}}
{"query":{"user":"5"},"prediction":{"itemScores":[{"item":"1","score":24},{"item":"4","score":14}]}}
```
