Fix issues found by pylint 2.0
Resolve:
 - no-else-return
 - useless-object-inheritance
 - useless-return
 - consider-using-set-comprehension
 - consider-using-in
 - logging-not-lazy

Ignore:
 - not-an-iterable - false possitives for asyncio coroutines

Ignore all the above in qubespolicy/__init__.py, as the file will be
moved to separate repository (core-qrexec) - it already has a copy
there, don't desynchronize them.
