Public bug reported:

Certain backends require other modules, ncftp for FTP, sftp for SSH,
etc..  If the user is not going to be using these modules, it should not
be a requirement to have them on the system.  I propose that we surround
all backend imports with a try/except and that all modules should check
requirements at import time prior to calling register_backend.  If a
backend fails to load, the default should be silence, however a
verbosity of INFO or better should show why.

** Affects: duplicity

Backend imports should be made optional
