    Fix AppCatalog to use 'marker' attribute for pagination

    Glance-like interface provides us with 'has_more_data' flag and
    'marker' pointing to the next page data set. That means that
    AppCatalog should drop link to previous page of Applications as well
    as current page number - they both are not supported by standard OS
    api.

    Also:
    * do not pass category as a part of murano:index url, pass it as a
      part of query-string (as well as marker);
    * refactor filling 'Latest Apps' section: inside get_context_data()
      remove invalid app_id-s from session (i.e. because those packages
      were deleted). This change is needed because we may no longer know
      all existing packages after a single request to AppCatalog
      IndexView.
