Bug: 28705665 Change-Id: Ibdab4631f0e692b8a291faecdeb4a6062f906ea5
Refactored the directory structure so that services can be optionally excluded. This is step 1. Will be followed by another change that makes it possible to remove services from the build. Change-Id: Ideacedfd34b5e213217ad3ff4ebb21c4a8e73f85
