[SPARK-20011][ML][DOCS] Clarify documentation for ALS 'rank' parameter
## What changes were proposed in this pull request?
API documentation and collaborative filtering documentation page changes to
clarify inconsistent description of ALS rank parameter.
- [DOCS] was previously: "rank is the number of latent factors in the
model."
- [API] was previously: "rank - number of features to use"
This change describes rank in both places consistently as:
- "Number of features to use (also referred to as the number of latent
factors)"
