This PR introduces the first step in refactoring the event handling system to better
support multiple values in a single event, which will help reduce allocations when
processing events. This is part of a larger effort to improve performance and reduce
memory allocations in the statsd exporter.
Changes:
- Add new `MultiValueEvent` interface that supports multiple values per event
- Add `MultiObserverEvent` implementation for handling multiple observations
- Add `ExplodableEvent` interface for backward compatibility
- Add `Values()` method to existing event types
- Add comprehensive tests for new interfaces and implementations
This change is the foundation for future improvements that will:
1. Move explosion logic to a dedicated package
2. Update the line parser to use multi-value events
3. Modify the exporter to handle multi-value events directly
4. Eventually remove the need for event explosion
The changes in this PR are backward compatible and don't affect existing functionality.
