Moved common functionality to base classes for code reuse. Refactored
googlephotos, reader and gmail workloads to take advantage of the new
base class methods and removed total test time metric.
New methods for BaseUiAutomation:
uiDeviceVertPinchIn, uiDeviceVertPinchOut
New methods for UxPerfUiAutomation:
uiObjectVertPinchTest, writeResultsToFile, startDumpsysSurfaceFlinger,
startDumpsysSurfaceFlinger, startDumpsysGfxInfo, stopDumpsysGfxInfo
New class for UxPerfUiAutomation:
GestureTestParams
A new workload to perform standard productivity tasks within
Googlephotos. Each user event/step is timed and reported back as a
metric. Dumpsys also captures SurfaceFlinger logs for each event for
post analysis.
