Detect when ES can be replaced with lodash

[gajus]

e.g.

Object.keys(commands)
    .map((key) => {
        return commands[key];
    })
    .forEach((cmd) => {
        if (cmd.yargsSetup) {
            cmd.yargsSetup();
        }

        if (cmd.examples) {
            cmd.examples();
        }
    });

warn that Object.keys can be replaced with _.keys.

This would be great for consistency.

This is already implemented in other project: https://github.com/wix/eslint-plugin-lodash3/blob/master/docs/rules/prefer-lodash-method.md
