Add new restic handler

See merge request !48

Without it, the single-quoted paths on the command-line are interperted
literally, leading restic find all include paths invalid...

Make this consistent with the borg handler. Allows users to use paths
that include spaces in them and prevents shell globbing when the restic
command is called. According to the restic docs, if glob paths are
needed, they should be read from a file (--files-from).

Making this consistent with the borg handler. Users should think about
what they need to be backup. The example file is there to provide a
baseline.
