Add the ability to quick-provision without lab cache servers Running m2n AU tests locally is very painful for first-time users since it requires extensive SSH configuration to the lab cache servers. SSH access to lab cache servers from your workstation is also in a weird place in terms of support right now, with some sources recommending against the steps needed to set it up. To provide a much easier alternative, I made some edits to provisioner.py to allow using the public throwaway cellular bucket as the source for the quick-provision artifacts, and applied these to au_Basic. This way, no special setup is needed to run m2n tests for the first time (except for possibly copying your GS .boto key into your chroot) - no ssh access, no shadow_config.ini, no job_repo_urls. I still need to update the other tests besides au_Basic with the changes for running without job_repo_url, I will address those in follow-up CLs.

Autotest is a framework for fully automated testing. It was originally designed to test the Linux kernel, and expanded by the ChromeOS team to validate complete system images of ChromeOS and Android.
Autotest is composed of a number of modules that will help you to do stand alone tests or setup a fully automated test grid, depending on what you are up to. A non extensive list of functionality is:
A body of code to run tests on the device under test. In this setup, test logic executes on the machine being tested, and results are written to files for later collection from a development machine or lab infrastructure.
A body of code to run tests against a remote device under test. In this setup, test logic executes on a development machine or piece of lab infrastructure, and the device under test is controlled remotely via SSH/adb/some combination of the above.
Developer tools to execute one or more tests. test_that for ChromeOS and test_droid for Android allow developers to run tests against a device connected to their development machine on their desk. These tools are written so that the same test logic that runs in the lab will run at their desk, reducing the number of configurations under which tests are run.
Lab infrastructure to automate the running of tests. This infrastructure is capable of managing and running tests against thousands of devices in various lab environments. This includes code for both synchronous and asynchronous scheduling of tests. Tests are run against this hardware daily to validate every build of ChromeOS.
Infrastructure to set up miniature replicas of a full lab. A full lab does entail a certain amount of administrative work which isn't appropriate for a work group interested in automated tests against a small set of devices. Since this scale is common during device bringup, a special setup, called Moblab, allows a natural progressing from desk -> mini lab -> full lab.

You need to run utils/build_externals.py to set up the dependencies for pre-upload hook tests.
