Addresses 4 critical OpenTelemetry span issues in LiteLLM:
Issue #3: Remove redundant attributes from raw_gen_ai_request spans
- Removed self.set_attributes() call that was duplicating all parent span
attributes (gen_ai.*, metadata.*) onto the raw span
- Raw span now only contains provider-specific llm.{provider}.* attributes
- Reduces storage and eliminates search confusion from duplicate data
Issue #4: Prevent attribute duplication on litellm_proxy_request parent span
- When litellm_request child span exists, removed redundant
set_attributes() call on the parent proxy span
- Child span already carries all attributes; parent duplication doubles
storage and complicates search
Issue #5: Fix orphaned guardrail traces
- Guardrail spans were created with context=None when no parent proxy span
existed, resulting in orphaned root spans (separate trace_id)
- Added _resolve_guardrail_context() helper to ensure guardrails always
have a valid parent (litellm_request or proxy span)
- Applied fix to both _handle_success and _handle_failure paths
Issue #8: Add gen_ai.response.id for embeddings and image generation
- EmbeddingResponse and ImageResponse types don't have provider response IDs
- Added fallback to standard_logging_payload["id"] (litellm call ID) for
correlation across LiteLLM UI, Phoenix traces, and provider logs
- Completions still use provider ID (e.g. "chatcmpl-xxx") when available
Tests added:
- TestRawSpanAttributeIsolation: Verify raw span has no gen_ai/metadata attrs
- TestNoParentSpanDuplication: Verify parent span doesn't get duplicated attrs
- TestGuardrailSpanParenting: Verify guardrails are children (not orphaned)
- TestResponseIdFallback: Verify response ID set for all call types
All existing OTEL tests pass (73 passed, 14 pre-existing protocol failures).

When OpenTelemetry is configured via the UI, only OTEL_ENDPOINT and
OTEL_HEADERS are set, but OTEL_EXPORTER is not specified. This caused
the exporter to default to "console", meaning traces were printed to
stdout instead of being sent to the configured endpoint.
This fix adds logic in OpenTelemetryConfig.__post_init__ to automatically
infer "otlp_http" as the exporter when an endpoint is specified but the
exporter is still the default "console".
Fixes issue reported by Elastic team where traces weren't being sent
to their OTEL endpoint when configured through the LiteLLM UI.
