dovetail tool: reorganize dovetail_config.py and modify related files

1. move all sentencs and functions into class DovetailConfig
2. delete dict container_config for it has been replaced by dovetail_config
2. modify files that import dovetail_config, including container.py, parser.py,
   report.py, run.py, dovetail_logger.py and testcase.py
