Add flake8 linting to project The GDS Way™[1] recommends using Flake8 to lint Python projects. This commit takes the Flake8 config from Digital Marketplace API[2] and removes the bits we don’t need. It changes the `max_complexity` setting to 14, which is the most complex code we have in this repo currently (we shouldn’t be writing code _more_ complex than what we already have). This commit also fixes the errors found by Flake8, which includes 6(!) tests which were never getting run because they had the same names as existing tests. Here is a full list of the errors that were found and fixed: ``` ./app/__init__.py:2:1: F401 're' imported but unused ./app/__init__.py:4:1: F401 'json' imported but unused ./app/__init__.py:8:1: F401
