Commit Message

make AutoValue work in PubSub

This commit digs us out of the AutoValue dependency hell.

Previously
- We require Guava 20 for its Stats class.
- Guava source has a `@CanIgnoreReturnValue` annotation,
  this annotation is in errorprone package.
- Errorprone package required Java8 to run. So, I just took dependency
  on it without running to make the build pass in both 7 and 8.
- Errorprone shades class javax.lang.model.type.IntersectionType.
  This class is Java8-only, but because it wasn't run, it didn't cause a problem.
- AutoValue conditionally loads IntersectionType.
  It catches Exception and behaves properly if the class is not found;
  this is why it works on Java 7.
  However, because of the previous step, we have the class in our path.
  Because the class is 8-only, JVM7 loading it results in
  UnsupportedVersionError. This is an Error and not an Exception,
  and so AutoValue (probably wisely) ignore it and crashes.

The fix is simple.
Since https://github.com/GoogleCloudPlatform/google-cloud-java/pull/1480
already removed Stats, we can just go back to Guava 20.

@garrettjonesgoogle is full of wisdom!
