Steve Karg b357bca5dd Converted device object test to use common read-write property test. Extended the basic BACnet device object example API. (#1106) 
* Converted device object test to use common read-write property test. Extended the basic BACnet device object example API.

* Created BACnet/IP and COV test mocks to enable device object testing with less dependencies.
