commit 80e3b8f96c082d08bba352e032e8a8fb08e30e8d
Author: David Haddock <dhaddock@chromium.org>
Date: Sun Apr 22 18:42:30 2018

Refactor server side code a bit ahead of last few AU tests.

We want to share common code between the client and server base classes.
To do this I have introduced a new class update_engine_util. It will
hold common variables and methods.

The client and server base classes will then use multiple inheritance.
To inherit from update_engine_util and the standard autotest test class.

The differences between the client and server is the run() function
used: either utils.run for client or host.run for server. The will be
defined in the initialize() function of each base class.

Add a test which interrupts a regular update.

We already have a test for interrupting an update during OOBE.
This will do the same for a regular update.

The test will log into Chrome, start an update, then log out.
It will reboot, pull network, suspend/resume.
It will add a new user and crash the browser.
Then ensure that the update completes successfully.
