Fixed all compilation errors in S3 API IAM tests by removing obsolete
filerAddress parameters and adding missing role store configurations.
### Compilation Fixes:
- Removed filerAddress parameter from all AssumeRoleWithWebIdentity calls
- Updated method signatures to match stateless STS service API
- Fixed calls in: s3_end_to_end_test.go, s3_jwt_auth_test.go,
s3_multipart_iam_test.go, s3_presigned_url_iam_test.go
### Configuration Fixes:
- Added missing RoleStoreConfig with memory store type to all test setups
- Prevents 'filer address is required for FilerRoleStore' errors
- Updated test configurations in all S3 API test files
### Test Status:
- ✅ Compilation: All S3 API tests now compile successfully
- ✅ Simple tests: TestS3IAMMiddleware passes
- ⚠️ Complex tests: End-to-end tests need filer server setup
- 🔄 Integration: Core IAM functionality working, server setup needs refinement
The S3 API IAM integration compiles and basic functionality works.
Complex end-to-end tests require additional infrastructure setup.
- Updated S3IAMIntegration constructor to accept filerAddress parameter
- Fixed all NewS3IAMIntegration calls in tests to pass test filer address
- Updated all AssumeRoleWithWebIdentity calls in S3 API tests
- Fixed glog format string error in auth_credentials.go
- All S3 API and IAM integration tests now compile successfully
- Maintains runtime filer address flexibility throughout the stack
