Put a cap on our cyclomatic complexity

flake8 has support for cyclomatic complexity (Mccabe) currently our
worst offender has a complexity of 67 (25 is considered very bad). So
set our max-complexity to 68 so we at least don't make things any worse.

This is the first step in bringing this number down to 25 or so.
