LoggingSupport (apache-cassandra API)

All Known Implementing Classes:

LogbackLoggingSupport, NoOpFallbackLoggingSupport
```
public interface LoggingSupport
```
Common abstraction of functionality which can be implemented for different logging backend implementations (slf4j bindings). Concrete implementations are dynamically loaded and instantiated by LoggingSupportFactory.getLoggingSupport().
