Use eslint for JavaScript about drupal-mode HOT 2 OPEN

ESLint is the official linting tool for Drupal 8 now (see #2274223) so we should probably use that instead (although there is now flymake-eslint.el (yet).

from drupal-mode.

Theres ESLint support in flycheck, it just requires one to disable the jshint checker.

The question is whether to just disable jshint buffer locally for Drupal js files, and assume that eslint is available, or do it the proper way and detect whether eshint is installed and only disable jshint in that case. The latter is more proper, but the former is probably easier.

Though flycheck has flycheck-may-use-checker which can tell us whether a checker may be used in the current buffer, which should make it fairly easy to fix up the flycheck-disabled-checkers in some hook.
