Templates should integrate eslint

[oliversturm]

Subject says it - currently I need to integrate eslint myself, which is a hassle. It should be part of templates we deliver.

What I do to integrate it is this. Install modules:

npm install --save-dev eslint eslint-plugin-react

Initialize for the backend projects in main project folder - run node_modules/.bin/eslint --init and answer questions for server-side JS.

Enter client folder and initialize for the frontend project - run ../node_modules/.bin/eslint --init and answer questions for client-side JS using React.

And the hooks plugin should also be included - it's a standard create-react-app thing these days.

Good proposal. We'll take it into account when perform cleaning up templates #1579

One comment to add: I found recently that another separate eslint config is required for the test folder.
