Remove use of hacking lib
Current hacking library pins on a version of flake8 that is too
old to recognize some py3.5'isms.
Adds ignores for:
E305 expected 2 blank lines after class or function definition
E402 module level import not at top of file
F405 'AnsibleModule' may be undefined, or defined from star imports
W503 line break before binary operator
