pseq: Create Chassis class
Create a C++ Chassis class that corresponds to the JSON "chassis" object
in the config file.
Eventually more function will be added to this class, but for the
initial version only implement the required support for the JSON
properties.
Create automated test cases for the new class.
Tested:
* Ran automated test cases.
