Description

There are two useful stats exposed by postings that are easy to also expose in points: size, which is the total number of points indexed, and getDocCount, which is the total number of documents that have at least one point.

Like the other point values API fixes, I think we should do this for 6.0, since otherwise if we add it later we'll have to annoyingly handle the "-1" back compat case.
