[SPARK-5895][ML] add vector slicer
JIRA issue [here](https://issues.apache.org/jira/browse/SPARK-5895).
I have some thoughts of `AttributeGroup`:
1. End-user is hard to add `AttributeGroup` or `Attribute` with `DataFrame`;
2. The constructor of `AttributeGroup` cannot covariance with subclass of
`Attribute`, say, it requires an `Array[Attribute]`, but I cannot give it an
`Array[NumericAttribute]`.
