Implement dual-mode testing infrastructure for all DMap integration tests:
- Update TestDMap1, TestDMap2, TestDMap3, TestDMap4Append, TestDMap5CSV to run in both serverless and server modes
- Create dmap_server_helpers.go with server-based testing utilities and SSH connection management
- Add small test data files to work within server channel buffer limitations:
- small_mapr_testdata.log (16 lines from original mapr_testdata.log)
- small_dmap5.csv.in (reduced CSV input for DMap5 testing)
- Expected output files for all DMap test variants in server mode
- All tests now establish SSH connections between dmap client and dserver binary when in server mode
- Maintain backward compatibility with existing serverless test functionality
Tests verified passing in both modes:
- TestDMap1: MapReduce query variations with different WHERE clauses and SET operations
- TestDMap2: Ordered aggregation queries with GROUP BY and ORDER BY
- TestDMap3: Multiple file processing with reduced file count for server mode
- TestDMap4Append: File append functionality with multiple runs
- TestDMap5CSV: CSV format input/output processing with custom aggregations
Technical improvements:
- Consistent file naming between server and serverless modes to avoid path conflicts
- Proper SSH trust handling with --trustAllHosts flag
- Multiple server helper functions for single-run and multi-run scenarios
- Intelligent file comparison selection (compareFiles vs compareFilesContents)
