[WIP] Provider dialogs

[himdel]

(The first two commits are #4181.)

This adds a way for toolbar buttons to open modals somehow defined by the provider.

Added the button to Compute > Clouds > Providers list - first button - Magic.

Clicking it will fire a http request (right now, call_the_endpoint fakes it) to get additional data,
and based on the response, will render a react component (previously added to the registry by ManageIQ.component.addReact('name', ...)) or the angular dialog-user component (TODO).

Right now this works for react:

(the styling is wrong for now because .modal-body > .container doesn't work, but removing the .container element fixes it)

[himdel]

And almost there with dialog-user..

(except right now, it's trying to render dialog-user multiple times)

EDIT: fixed, no more errors :)

[himdel]

So, @martinpovolny the important bits would seem to be ready,

What's probably missing right now is integrating the modal buttons with the form buttons. as that requires cooperation from the component.

Maybe we could use something like #3509 to separate the buttons from the component. Or maybe we can just add options to renderModal for now, and pass the button defs and callbacks there.

@himdel : we don't need this to be done as Modal dialog, it can take the whole page if it's easier to do. Any of the 2 would work.

Well at least for now ;-)

@martinpovolny that overflowing dialog is my fault. I thought that patternfly grid layout will work everywhere... it can be fixed very easily..

[martinpovolny]

@Hyperkid123 : then, please, fix this and ping me in the PR. Thx!
