abstract class Redis_Cache_Base in Redis 7.3

@todo

• Improve lua scripts by using SCAN family commands
• Deambiguate why we need the namespace only for flush*() operations
• Implement the isEmpty() method by using SCAN or KEYS

Hierarchy

• class \Redis_AbstractBackend implements Redis_BackendInterface
  • class \Redis_Cache_Base
