    Address python3 pylint errors and warnings

    This commit addresses issues detected by the updated python3 pylint:
    - Added a return code to the report_app_dependencies function to
    satisfy the E1111 error reported.
    - Added line-specific pylint disable for unused-argument for cases
    where the inclusion of such arguments in the function signature was
    intentional.
    - Added line-specific pylint disable for the duplicate-except case
    found, as python3 has merged IOError into OSError, while these are
    separate exceptions in python2. Once we're running solely on python3,
    this duplicate exception handling can be dropped.
