Description

Spinoff from LUCENE-5298: ValueSource and FunctionValues are abstract APIs which exist under the queries/ module. That causes any module which wants to depend on these APIs (but not necessarily on any of their actual implementations!), to depend on the queries/ module. If we move these APIs under core/, we can eliminate these dependencies and add some mock impls for testing purposes.

Quoting Robert from LUCENE-5298:

we should eliminate the suggest/ dependencies on expressions and queries, the expressions/ on queries, the grouping/ dependency on queries, the spatial/ dependency on queries, its a mess.

To add to that list, facet/ should not depend on queries too.
