Merge pull request #10381 from AlanCoding/tox_configish

Enter flake8 rules in tox config as actual config entries

I really like to do things like
flake8 awx/main/models

but this is made impractical where running flake8 for the project carries with it an assumption that you will pass a specific set of options.

Blessedly, flake8 is flexible in their config options so that it may weather the storm of python project config wars.
