feat: migrate to ES2018 syntax and drop obsolete configs

BREAKING CHANGES:

* ES2018 is the default syntax for `recommended`. If your source code uses newer syntax version,
  make sure to set `parserOptions#ecmaVersion` accordingly.
* `es5` and `es6` configs are removed. Use `node` or `browser` instead, depending on your environment.
