Add eslint rules to avoid usage of unsupported node features?

[karfau]

@XhmikosR suggested to make use of some of these eslint rules: https://github.com/mysticatea/eslint-plugin-node
Which work based on the engines field in package.json.

We are already using the eslint-plugin-es5, we should check if there is an overlap and if it makes sense, since node is not our only supported environment.
