[SPARK-15502][DOC][ML][PYSPARK] add guide note that ALS only supports
integer ids
This PR adds a note to clarify that the ML API for ALS only supports
integers for user/item ids, and that other types for these columns can be used
but the ids must fall within integer range.
(Refer [SPARK-14891](https://issues.apache.org/jira/browse/SPARK-14891)).
Also cleaned up a reference to `mllib` in the ML doc.
## How was this patch tested?
Built and viewed User Guide doc locally.
