In T340552, the official PHP OpenTelemetry client was effectively rejected for inclusion in MediaWiki due to its size. Implement a minimal tracing library instead that eschews conformance with the OTEL client specification in favor of simplicity, while remaining capable of emitting trace data in OTLP format and thus retaining compatibility with any ingestion endpoint capable of handling OTLP. In its current state, the library supports a basic feature set that should be sufficient for basic tracing integration: * Span creation, inclusive span activation and automatic parent span assignment, * Span attributes and span kinds, * Basic resource (process/request)-level metadata generation, * Data export over OTLP. Additional functionality, such as trace propagation, can then be incrementally added to the library. Bug: T340552 Change-Id: Ibc3910058cd7ed064cad293a3cdc091344e66b86

The telemetry library implements a minimal OpenTelemetry tracing client
that is compatible with the OTEL data model but not compliant with the OTEL client specification.
This was developed to avoid taking a dependency on the official OpenTelemetry PHP client, which was deemed too complex to integrate with MediaWiki (T340552).
telemetry requires a PSR-3 logger, a PSR-18 HTTP client and a PSR-17 HTTP factory.
