Converted User Visual Settings form to be API-driven with DDF

[skateman]

• Timezones - Add the list of available rails timezones to the base endpoint manageiq-api#973
• Languages
• Start pages - Introducing a simple GET-only endpoint for shortcuts manageiq-api#970

Fixes #6934

Multiselect dropdowns with search capability are crashing, fix is here #7540

Are there any unmerged dependencies?

Trying to save the form, I get a 400: Invalid attribute(s) settings specified for a user

(PATCH http://localhost:3000/api/users/10000000000001
Returns {"error":{"kind":"bad_request","message":"Invalid attribute(s) settings specified for a user","klass":"Api::BadRequestError"}})

(Also, all ddf selects now seem to only react to the second click. Once it's focused you can click to expand, but the first click only focuses, not expands. But that's also happening on master.)

Seems like a bug in the API ManageIQ/manageiq-api#1001

@himdel should be fine now, the dropdown issue is probably coming from DDF

[himdel]

Agreed, the dropdown issue is not ours, so assuming that will likely be fixed by the carbon switch.

Testing again :)
