Angular source re-organization

[Tyr Johanson]

The Angular source will benefit from re-organization to
1) align module names with their directory structure
2) make it clear what is "framework" code (reusable utilities), what is "core business logic" of the horizon UI, and what is code that bootstraps the application.

See https://review.openstack.org/#/c/176152/ for an example of the full set of proposed changes. The ideas in that patch are well supported by cores and the PTL, however that patch is too large to be easily reviewed and merged. Instead, create a series of smaller, dependent patches that incrementally make the desired improvements.

List of in-progress changes:
1) Create a "framework" directory
2) Create a "util" directory and populate it with utilities
3) Create a "widgets" directory and populate it with the widgets
4) Align the module names with their directory structure
5) Align constant, service and factory names with their modules
6) Move API support files to openstack_dashboard
7) Move horizon/js/angular/filters to framework/utils
8) Refactor the "hz" module to "hz-app" and move as much "legacy" code
   as possible into the new structure (out of horizon/js/angular)

List of additional possible changes:
?) Align controller names to include their module
?) Clean up unneeded dependencies
   - We may consider moving wizard.js dependency on 'ui.bootstrap' as a dependency to horizon module.
   - It seams we can remove `horizon.framework.util.i18n` from here.

    ngReorg - Align constants, factories and services

    This commit makes injectable names consistent to include
    the module as a prefix. This reduces confusiong about
    exactly which item is being injected.

    It also simplifies the naming scheme for the Angular-based
    API modules.

    This is one step in a larger effort to restructure the Angular

    ngReorg - Create dashboard-app

    This is the last patch of this ngReorg series!!

    This commit attempts to refactor the "hz" module and horizon.js
    into "dashboard-app" because the code is actually bootstrapping
    the default dashboard application, created using framework and
    openstack_dashboard pieces. Ideally, this moves into a directory
    that is a peer to openstack_dashboard, but for now, it is at
    least grouped together with a name that reflects its purpose.

    This was the last step in a larger effort to restructure the Angular
    source. See https://review.openstack.org/#/c/176152/ for the
    full set of planned changes.

    The next refactoring effort (not addressed by this patch series)
    is to restructure the Django templates so that
    horizon.dashboard-app can be moved OUT of horizon/horizon.
