Possibility to use org.springframework.cache.support.NoOpCacheManager.NoOpCache as public class as NoOpCacheManager.

I just explain my use case to use NoOpCache as a client.

I configure some caches via in my spring-boot microservice.
Some are server side, some are client side via interface designed with feign/spring-cloud annotation and @Cacheable
For server side, I want always to use cache.
For client side, depending of my microservice, I want to activate or not some caches, for instance, on a spring-batch microservice I want to cache. Just for information, my different interface of my feign client with @Cacheable are shared between the different microservices via client jar of my microservice.

So my configuration should be in some case like

    @Bean
    public CacheManager cacheManager() {
        final SimpleCacheManager cacheManager = new SimpleCacheManager();
        cacheManager.setCaches(Arrays.asList(
                new NoOpCacheManager.NoOpCache("bar"),
                new ConcurrentMapCache("foo")));
        return cacheManager;
    }

Can you just see NoOpCache as public class or have something close.
Of course, I can have a basic NoOpCache on my side but it should be by default in spring-cache.

Stéphane Nicoll, let's simply move NoOpCache to a top-level class in cache.support...

NoOpCache is now a top-level public class. Thanks!
