Implement WidgetFactory for CloudSet

[Vlatombe]

Downstream of https://github.com/jenkinsci/jenkins/pull/7932

This lets the plugin leverage the new extension point to show the stats widgets in the CloudSet view where it makes sense the most.

Ux doesn’t look good to me I probably wouldn’t add widgets to this page I don’t think it gives any value.

Well there was a widget already; this is basically moving it to the clouds view rather than dashboard.

It's duplicating it isn't it?

A link to the stats in the app bar would look better I think not putting it in the sidebar which makes the page look unbalanced

Yes, I figure the plugin would need some work to leverage the new real estate provided by the manage clouds screen.

Closing as the tentative change was removed from the core api.
