Angularize Swift Panel

Angularize Swift Panel

Summary
=======

Move OpenStack Dashboard Swift panel rendering logic to client-side, using AngularJS.

Motivation
========

The current django based Swift interface is very basic, and not pleasant to use. We will aim to provide a much richer experience to users.

Description
=========

The following features will be added to Horizon:

a) Angularized swift panel
* a basic interface that uses swift containers and pseudo-folders to present to the user what looks like a hierarchical file system.
* client side support for pagination, (limited) searching and (limited) sorting

b) Services in Horizon REST API
* access to swift configuration via the /info endpoint.
* access to objects stored in swift.
* over time access to optional features that may be enabled in swift (for example server side copying)

UX
==

Wireframes, Mocks, Videos and UI Markup
---------------------------------------

Invision will be used to provide a place where the UX team can propose designs for use in this panel.

Testing
======

Reviewers will be able to pull the patch from Gerritt. Any specific information needed to test the changes will be provided in the commit message.
