Known direct subclasses

DeviceImageZipFlashingTargetPreparer, SideloadOtaTargetPreparer

DeviceImageZipFlashingTargetPreparer	A target preparer that flashes the device with device images provided via a specific format.
SideloadOtaTargetPreparer	A target preparer that performs sideload of a specified OTA package, applies the package, waits for device to boot up, and injects the device build properties to use as build info This target preparer assumes that the device will be in regular adb mode when started, and will ensure that the device exits in the same mode but with the newer build applied.

An abstract ITargetPreparer that takes care of common steps around updating devices with a device image file from an external source (as opposed to a build service). The actual update mechanism is delegated to implementor of subclasses.
