Keep file removal, but do not remove file when encoding video until
everything is encoded. Also limit the response from GCS Post. Using
blob_to_dict leads to threading issues (due to signed url generation).
Good fix if you want to get involved in Pillar development!
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.
