Upgrade semconv to v1.39.0

[MrAlias]

Resolve #8404

Upgrade go.opentelemetry.io/otel/semconv to v1.39.0, including updates across all instrumentation and detector modules.

• The semantic conventions v1.39.0 release introduces breaking changes, including:

  • rpc span and metric attributes have been renamed to align with naming guidelines:
    • rpc.system → rpc.system.name (values: grpc, grpc_web, connectrpc, thrift, dubbo, etc.)
    • rpc.method and rpc.service have been merged into a fully-qualified rpc.method attribute
    • rpc.client|server.duration → rpc.client|server.call.duration (unit changed to seconds)
    • rpc.grpc.request.metadata/rpc.grpc.response.metadata → rpc.request.metadata/rpc.response.metadata
    • rpc.grpc.status_code → deprecated in favor of rpc.response.status_code
    • rpc.jsonrpc.request_id → jsonrpc.request.id
    • rpc.jsonrpc.version → jsonrpc.protocol.version
  • system and process metrics:
    • *.linux.memory metrics renamed to *.memory.linux
    • system.process.status → process.state
    • system.paging.type and process.paging.fault_type → system.paging.fault.type
  • peer.service attribute has been deprecated in favor of service.peer.name

  See semantic-conventions v1.39.0 release and v1.38.0 release for complete breaking change details.

Pull request overview

This pull request upgrades the semantic conventions from v1.37.0/v1.38.0 to v1.39.0, introducing significant breaking changes across the OpenTelemetry contrib repository. The upgrade includes renaming RPC attributes (rpc.system → rpc.system.name), merging rpc.service and rpc.method into a fully-qualified rpc.method, updating gRPC status codes, and migrating from peer.service to service.peer.name.

Changes:

• Updated semantic convention imports from v1.37.0 to v1.39.0 across all instrumentation, bridges, detectors, and examples
• Modified RPC instrumentation to use merged rpc.method attribute (combining service and method names)
• Updated attribute functions in AWS SDK instrumentation with new MethodAttr() and deprecated old functions
• Changed gRPC status code attributes from integer to string values
• Updated HTTP instrumentation to use service.peer.name instead of deprecated peer.service
