lint: Up-rev hacking

Without up-reving hacking python 3.12 can't be used for pep8/flake8
checks. Also address a few new pyflakes issues that seem reasonable
to enforce:

   E275 missing whitespace after keyword
   H214 Use assertIn/NotIn(A, B) rather than
        assertTrue/False(A in/not in B)
   H211 do not compare types, use assert{Is,IsNot}Instance

Add F811 (redefinition of unused 'function'), as this check makes
client.py fail.

And noqa some longer lines that we're happy to carry.
