Migrating the NetworkScoreManager.requestScores() method to use an
IPC rather than a broadcast.
Defined the new IPC in the AIDL files for NetworkScoreService and
NetworkRecommendationProvider. Added a no-op implementation in
NetworkScoreService and a full implementation in
NetworkRecommendationProvider (plus tests).
Test: adb shell am instrument -e class android.net.NetworkRecommendationProviderTest -w com.android.frameworks.coretests/android.support.test.runner.AndroidJUnitRunner
