Ignoring some linter errors to fix imports

[rkty13]

Fix for this issue:

➜  backend (master) ✔ pipenv run start
Traceback (most recent call last):
  File "app.py", line 1, in <module>
    from api import app
  File "/Users/robertkim/dev/personal/number-eleven/backend/api/__init__.py", line 4, in <module>
    from api.v0 import api_v0
  File "/Users/robertkim/dev/personal/number-eleven/backend/api/v0/__init__.py", line 3, in <module>
    import api.v0.routes  # pylint: disable=cyclic-import
  File "/Users/robertkim/dev/personal/number-eleven/backend/api/v0/routes.py", line 3, in <module>
    from api.v0 import api_v0
ImportError: cannot import name 'api_v0' from 'api.v0' (/Users/robertkim/dev/personal/number-eleven/backend/api/v0/__init__.py)

api_v0 can't be imported in routes.py because it's being imported in api.v0 module before api_v0 is initialized.
