Fix JdkObsolete warnings

[mfvanek]

There are some warnings like:

LFUCache.java:94: warning: [JdkObsolete] It is very rare for LinkedList to out-perform ArrayList or ArrayDeque. Avoid it unless you're willing to invest a lot of time into benchmarking. Caveat: LinkedList supports null elements, but ArrayDeque does not.
        final List<Map.Entry<K, V>> evictedItems = new LinkedList<>();
                                                   ^
    (see https://errorprone.info/bugpattern/JdkObsolete)
  Did you mean 'final List<Map.Entry<K, V>> evictedItems = new ArrayList<>();'?

Need to fix them all
