Progress bar doesn't displayed at image upload

[Vadym Markov]

"Create image" modal windows should render progress bar during image upload, immediately after "Create image" button pressed. It disappears when image loaded. Screenshot of expected behavior is attached

    Periodically check item status if it in transition state

    Several Angular based dashboards, such as images and snapshots,
    not regenerated after some item on this page changes its status
    from transition state.
    For example, an image may be shown forever in the "Creating" state
    with running progress bar. To improve UI this patch re-upload items
    list until some item in transition state.
    If status of item changed, then 'trackBy' field changed and
    Angular will re-render row with this particular item with
    ng-repeat-start directive and won't re-render all entire page.
