[merge-103][segmentation] Add support for experimental subgroups

Uses model score to select a subsegment for heuristic models. This
allows the model to provide specific scores for users and that can be
used to log synthetic field trials specific to those subsegment. The
metadata must define an extra subsegment discrete mapping that maps
model scores to subsegment enum.
