Chrome updater test framework

Anantha told me yesterday that she doesn't want to use pyauto for this framework
anymore. She wants to use chromedriver. Please check with her.

ALso, protector is currently disabled, and might soon get deleted.
See the converstaion and patchsets in
https://chromiumcodereview.appspot.com/10868053
Therefore it's not prudent to use protector as a use case for updater framework.

Yes, I did talk to her about it. She wanted me to replace the protector test
with a test similar to one of the tests from test_basic. So I went ahead and
made that change and renamed the protector_updater.py accordingly. Also, Anantha
said that we still might be able to use this framework for some scenarios, but
she also wanted me to create a version that uses ChromeDriver instead of PyAuto.
So I am just going to submit this sample test for now. I will create a new CL
for the framework that uses ChromeDriver.

+"""Runs Protector updater tests using two Chrome builds.
+
+Test requires two arguments: build url and chrome versions to be used, rest of 
+the arguments are optional. Specified builds are sorted before installation
+begins, meaning lowest version of Chrome gets installed first and then Chrome
+is updated using the next, higher version of Chrome. Install and Update, which
+are both handled by the base class, return a pyauto.PyUITest object. PyUITest
+object can then be used to run updater tests.
+
+Example:  
+    $ python protector_updater.py --url=<URL> --builds=19.0.1069.0,19.0.1070.0
