SPARK-4588 [MLLIB] [WIP] Add API for feature attributes
@mengxr
This is an early checkin to see if this is in the right direction at all.
- Should this have a counterpart "builder" class, or setters that make a
new copy of the object?
- In the JIRA you mention feature dimension. Dumb question, but is that
just the cardinality of categorical features?
- I structured it all with maps, and I wonder if that's OK
