> The class should be:  
> 1\. Thread-safe  
> 2\. Support caching for multiple clusters  
> 3\. Write cache to json file for debug purposes.
> In next jiras the class with be derived by ClusterConfigurationCache,
> ClusterTopologyCache and ClusterComponentsStatusCache.
> We have already a caching class for alerts. The jira should also rewrite it to
> use the base class.
