[SPARK-5424][MLLIB] make the new ALS impl take generic ID types
This PR makes the ALS implementation take generic ID types, e.g., Long and String, and expose it as a developer API.
TODO:
- [x] make sure that specialization works (validated in profiler)
srowen You may like this change:) I hit a Scala compiler bug with specialization. It compiles now but users and items must have the same type. I'm going to check whether specialization really works.
