Fixes #13444
Problem:
AWS Lambda for Java provides two handler interfaces:
com.amazonaws.services.lambda.runtime.RequestHandler
com.amazonaws.services.lambda.runtime.RequestStreamHandler
However, instrumentation for RequestStreamHandler is missing in the OpenTelemetry Java agent.
Fix:
Added instrumentation support for RequestStreamHandler.
Test:
Pass with green:
./gradlew spotlessCheck
./gradlew clean assemble
./gradlew instrumentation:test
./gradlew :smoke-tests:test
Manual end-to-end tests pass:
Backward Compatibility:
No risk of breaking existing functionality.
The change only adds instrumentation for RequestStreamHandler without modifying existing behavior for RequestHandler. Existing users not using RequestStreamHandler remain unaffected.
