Ryan Hitchman 77bf148460 backup: add --dry-run/-n flag to show what would happen.
This can be used to check how large a backup is or validate exclusions.
It does not actually write any data to the underlying backend. This is
implemented as a simple overlay backend that accepts writes without
forwarding them, passes through reads, and generally does the minimal
necessary to pretend that progress is actually happening.

Fixes #1542

Example usage:

$ restic -vv --dry-run . | grep add
