Two improvements to error handling and security:
1. weed/iam/sts/session_claims.go:
- Add logging for credential generation failures in ToSessionInfo()
- Wrap errors with context (session ID) to aid debugging
- Use glog.Warningf() to surface errors instead of silently swallowing them
- Add fmt import for error wrapping
2. weed/s3api/auth_signature_v4.go:
- Remove debug logging of actual access key IDs (glog.V(2) call)
- Security improvement: avoid exposing sensitive access keys even at debug level
- Keep warning-level logging that shows only count of available keys
This ensures credential generation failures are observable while protecting
sensitive authentication material from logs.
