Our CI (Travis & Kokoro) runs "gradle build", so we need to make
sure that all tasks used in the release process are called during
the build so that breakage can be caught earlier.
In order to stage the GAE folder we need gcloud to be present.
Therefore the Travis config is changed to install gcloud.

IntelliJ is complaining when this annotation is used on a base class that has no
actual runnable tests itself. The solution is different for different classes
depending on the existing pattern of where the @RunWith annotation is; for some,
it's simplest to move the annotation down to the few extending classes that are
missing it, whereas in others it's easiest just to annotate the base class as
abstract.
Fix or suppress deprecation warnings except those about GoogleCredential,
which is being handled separately.
The @SuppressWarnings("deprecation") annotation does not cover imports
even when it is at the class level. We removed imports of deprecated
classes and use their fully qualified names in class body.
* Consolidate testcontainer used by WebDriver test
Previously, we hard coded the version of the docker image for
provisioning Chrome browser and WebDriver server because the
version of the Chrome browser has to match the version of
the webdriver client, otherwise the screenshot test will fail.
Changing to use BrowserWebDriverContainer can delegate the match
to the library itself because it chooses the correct docker image
version based on the WebDriver version on our classpath.
* Increase maxColorDiff to 20
This is to supress the test flakness after switching to use
BrowserWebDriverContainer to provision browser and webdriver
service.
