DATAMONGO-1467 - Add support for MongoDB 3.2 partialFilterExpression for index creation.

We now support partial filter expression on indexes via Index.partial(…). This allows to create partial indexes that only index the documents in a collection that meet a specified filter expression. 

new Index().named("idx").on("k3y", ASC).partial(filter(where("age").gte(10)))

The filter expression can be set via a plain DBObject or a CriteriaDefinition and is mapped against the associated domain type.
