This PR adds an automatic gradle format checker and reformats all the *.gradle files. After this, new changes to *.gradle files will fail to build if not in good format, just like checkStyle failure.
The new jmh plugin fixes a warning for the newer version of Gradle.
The new AppEngine plugin still produces a warning, but updating it
anyway so people know that upgrading the plugin doesn't fix the problem.
The new android-maven plugin fixes a build problem with the newer
Gradle.
The Visual Studio fixes were necessary starting ~4.4.

describes the change in behavior.
There's nothing immediately being used as part of this update. It's just
to keep us current and to get us over that Visual Studio change hump.
