dovetail tool: package all logger initialization

1. For container.py, parser.py, report.py and testcase.py, they use functions
   in classes to create loggers. So each class will have its own logger.
2. run.py will create all the loggers by create_logs() function before the use
   of them. So logs will not be initialized until the call of create_logs().
3. Move logger in run.py into function main().
