Expression editor, rendered from the layouts/exp_editor partial (app/views/layouts/_exp_editor.html.haml).

Found in:

API changes in ManageIQ/manageiq-api#712

(we won't be doing autocomplete for now, but it seems we can use the proposed API to populate all the field choices)

The new component should also support accessibility, added it to the list of tasks there.
