Add support for Caffeine

[vladimir-bukhtoyarov]

It will be useful for bucket per key scenarios when distributed synchronization is unnecessary. Distributed synchronization can it can be unnecessary in the following use cases:

• Request stickiness is provided by a load balancer.
• Other use-cases where stickiness can be achieved by the application itself, for example, Kafka consumer.

@vladimir-bukhtoyarov found new issue in the version 7.3.0 as below.
Below code gives compile error as The constructor CaffeineProxyManager(Caffeine<Object,Object>, Duration) is undefined

Caffeine<Object, Object> caffeineCacheBuilder = Caffeine.newBuilder();
CaffeineProxyManager proxyManager = new CaffeineProxyManager(caffeineCacheBuilder, Duration.ofMinutes(2));

I am trying to use CaffeineProxyManager to maintain api-key specific buckets using caffein cache.

@pat246 hello,

Just use proper generic types for cache builder. You can find example in the tests.
