JCLOUDS-643: Fix Google and OAuth tests

https://issues.apache.org/jira/browse/JCLOUDS-643

This PR fixes failing live tests and updates static data for expect tests to match.  GCEL images are depracated, so this also update the default template options to use the Debian image as recommended by Google.  Added @Test annotations to several test classes which helps testng control threading, and avoid hitting network quota limits. Several other minor fixes to make unit and live tests run more consistently.
Ahh...this is only for the _live_ profile. So if you run `mvn integration-test` you'd get the unit tests followed later by the integration tests, but if you run `mvn integration-test -Plive` you'd only get the live integration tests?

In that case, fine! Thanks for explaining.
