Added pre-commit for running linters

[Arfey]

This is good feature but we running all linters from docker and it's not fast. Does anyone have any thoughts about this?

What do you mean? Run it in the CI directly

[Arfey]

CI as a solution. Thanks :) I will add ci file for gitlab.

I think that i have better idea. Right now all linters and static checker work with docker. It's works like that because i wonted that user after run create-ago-app don't install any additional packages. But, we can add mypy, flake8 and other packages in create-aio-packages to requirement packages in setup.py.

Add into .git/hooks/pre-commit:

#!/bin/sh
flake8 src/

After

chmod +x .git/hooks/pre-commit

For example?)

there's a tool which makes it more generic: https://pre-commit.com/
