[SPARK-19345][ML][DOC] Add doc for "coldStartStrategy" usage in ALS
[SPARK-14489](https://issues.apache.org/jira/browse/SPARK-14489) added the ability to skip `NaN` predictions during `ALSModel.transform`. This PR adds documentation for the `coldStartStrategy` param to the ALS user guide, and add code to the examples to illustrate usage.
## How was this patch tested?
Doc and example change only. Build HTML doc locally and verified example code builds, and runs in shell for Scala/Python.

Closes #17102 from MLnick/SPARK-19345-coldstart-doc.
