Android S - Request full tracking for raw measurements

[barbeau]

Is your feature request related to a problem? Please describe.

On Android S developer preview, it looks like there is now a way for apps to directly request disabling of duty-cycling when requesting raw measurements:
https://developer.android.com/reference/android/location/GnssMeasurementRequest#isFullTracking()

This would allow apps to do carrier phase measurements without needing the user to go into developer mode and disable duty cycling themselves as described here:

We should enable this by default on Android S and higher, and add an option in Settings to disable.

Describe the solution you'd like
Programmatically request full tracking of GNSS measurements when available on Android S and higher
