It is now possible to specify an encoding backend (at the moment only
zencoder) to take care of video variations encoding. Files transfer
happens directly on CGS (although any storage backend can be
supported). New requirements is the Zencoder Python library.
We introduce a new node_type, storage, which can support different file
storage backends and makes them available for browsing via dedicated
entry points in the application. We intend to keep pillar storage
agnostic and support both internal/local storages as well as
remote/hosted solutions.
