Merge lp:~kaffeekiffer/duplicity/azure-filename into lp:~duplicity-team/duplicity/0.8-series

[Frank Fischer]

Encode Azure back-end paths

This fixes lp:1840897 and restores consistent behaviour for Python2 _and_ 3, i.e.

duplicity-full-signatures.<timestamp>.sigtar
instead of
b'duplicity-full-signatures.<timestamp>.sigtar'
