[Form] More field states

[exoego]

Feature Request

Description

ui form supports several states: loading, success, error and warning.

Form's child element field supports only error state.
It would be great if field also support warning state, so warning-level check (can be submited but not recommended) can be visually expresed.

I don't think loading and success arenecessary for field, since it is unlikely to have success/loading in single field.

There could potentially be a use case for success - such as a visual password strength check, or showing something entered is valid or unique

Seems there already is loading https://fomantic-ui.com/elements/input.html#loading

@jamessampford loading is for Input not fields see https://jsfiddle.net/fjwk79xs/

That use-case sounds reasonable 👍

I will open a PR to add success and warning state to field.
loading may be added subsequently when use-case provided.

@exoego Might as well just add all the states so they are all supported (warning, info, success, error)
