[dashboard] Using v1 glanceclient causes Images panel to throw HTTPMultipleChoices

[Felipe Monteiro]

Currently, a HTTPMultipleChoices is being thrown when going to app-catalog/images in Horizon, with details: "Requested version of OpenStack Images API is not available."

Because the v1 glanceclient has already been deprecated and will probably be removed during Pike [0], it is necessary to remove glanceclient v1 dependency from murano dashboard as much as possible (if not all together). Especially since it is already causing problems in the dashboard.

    Update glanceclient from v1 to v2 to avoid deprecation errors.

    Currently, the app-catalog/images view in Horizon is throwing
    a 300 HttpMultipleChoices exception, with the details:
    "Requested version of OpenStack Images API is not available."

    Also, the glance v1 client is deprecated, so we should move to glance
    v2 wherever possible.

    This patch, therefore, removes glanceclient v1 dependency
    from murano dashboard as much as possible, especially
    given that Glance team intends on removing it from Pike [0].

    The only remaining places where the glanceclient v1 is kept
    are:
      - in _ensure_images in muranodashboard/packages/views.py,
        which uses copy_from functionality from glanceclient v1 to load
        images automatically.
      - done in ImportPackageWizard, which sets each package to
        public if the image that was uploaded was public
