Description

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.
