ConcurrentLinkedHashMap --> Caffeine when Java-8 based #3

When transitioning to requiring Java 8, please upgrade to Caffeine. The performance should be relatively the same and the per-instance memory usage should be smaller.

ConcurrentLinkedHashMap changes will continue to be minimal, even more so now, and driven by requests from Java 6 users unable to upgrade. Caffeine is ideally the upgrade path for Guava cache users too, which due to Android cannot be significantly modified.

Thanks. I'll definitely upgrade to Caffeine when migrating to Java 8.
