Add pylint py3 portability checks for the platform-armada-app

A lot of work has gone into making sure that StarlingX is python3
compatible. To ensure future compatibility, enable the python3
portability checks. Disable the checks that are raising errors.
Another set of commits will address the offending code.
Add following suppress warnings in pylint.rc:
- W1618: no-absolute-import
