Swift backend requires

[FlorianPerrot]

I try to run duplicity with swift protocol but "python-swiftclient" library is absent even if this library is present inside Pipfile.

$ docker run ... wernight/duplicity:latest FILENAME swift://test
gpg: WARNING: unsafe ownership on homedir '/home/duplicity/.gnupg'
BackendException: Swift backend requires the python-swiftclient library.
Exception: No module named 'pkg_resources'
