Improve RedisCache Manger implementation [DATAREDIS-481]

[spring-projects-issues]

Christoph Strobl opened DATAREDIS-481 and commented

Cache configuration shoule use something like the CacheBuilder as in CouchbaseCacheManager.

Consider:

• Optional cache locking
• Operate directly on RedisConnectionFactory
• Split up responsibilites between components (conversion/serialization, configuration, read/write ops,...)
• Follow contract defined by o.s.cache.Cache.
• Provide cache statistics
• (??? cache entry in Hash)
