Made changes thanks to code review

* Removed deprecated LOG_FD code from DummyAdapter
* Moved Adapter endpoints into a custom JSON object which will serve to store all endpoints in the future (client / Controller side)
* Renamed AdapterInstance to adapter_instance (snake case standard for variables)
* Inherited from the 'object' base class for awesomeness
* Edited the header of DummyAdapter.py to take ownership
* deleted the find_availaible_ip from VMUtils; now all modules use the one in BaseAdapter
