Fix SVID loading with robust DER parsing and cleanup integration test noise
- Implemented iterative DER parsing to handle concatenated SVID chains - Removed python-spiffe dependency in client apps for direct gRPC fetching - Silenced Keylime configuration warnings by providing minimal logging.conf - Improved service verification with retries in test scripts - Suppressed redundant gRPC connection tracebacks in bundle fetcher
