Subject: sample_updater: add non-streaming demo

SampleUpdater app was tested manually on a device.
There are unit tests for utility classes.

SampleUpdater app demonstrates how to use Android Update Engine to
apply A/B (seamless) update.
This CL contains demo of non-stream update using async update_engine,
which is accessed directly from an activity.
This app also shows logs from update_engine on the UI.
Instructions can be found in `README.md`.

- Create a UI with list of configs, current version, control buttons and a progress bar
- Add PayloadSpec and PayloadSpecs for working with update zip file
- Add UpdateConfig for working with json config files
- Add applying non-streaming update

Test: tested manually and unit tests for utilities
