This removes the possible large amount of data that was attached
to spans and it logs the data out. This change also removes the direct
dependency on the OTel SDK. approach for content in Spring AI.
Refactors the observability approach for content in Spring AI:
- Replace content observation filters with logging handlers
- Rename configuration properties to better reflect their purpose:
- `include-prompt` → `log-prompt`
- `include-completion` → `log-completion`
- `include-query-response` → `log-query-response`
- Add TracingAwareLoggingObservationHandler for trace-aware logging
- Replace micrometer-tracing-bridge-otel with micrometer-tracing
- Remove event-based tracing in favor of direct logging
- Update documentation to reflect these changes (add breaking-changes section)
- Rename includePrompt to logPrompt in observation properties. Updated in ChatClientBuilderProperties, ChatObservationProperties, and ImageObservationProperties.
