Why I did it
Recently additional sensors that were needed only for specific system added to all systems and caused errors.
How I did it
* Include CPU board and switch board sensors only on SN2201 system
* Fix issue in test_chassis_thermal, now it skips non existing thermals.
How to verify it
Run show platform temperature

- Why I did it
* To support systems with dynamic port configuration
* Apply lazy initialization to faster the speed of loading platform API
- How I did it
* Add module.py to implement dynamic port configuration (aka line card model)
* Adjust chassis.py, platform.py, thermal.py, sfp.py to support dynamic port configuration
* Optimize existing code
- How to verify it
Platform regression on MSN4700, MSN3800 and MSN2700, 100% pass
Unit test covers all new changes.
