replay: remove progress and info output

replay: remove progress and info output

The replay command will be changed in a follow up commit, so that it
will not update refs directly, but instead it will print on stdout a
list of commands that can be consumed by `git update-ref --stdin`.

We don't want this output to be polluted by its current low value
output, so let's just remove the latter.

In the future, when the command gets an option to update refs by
itself, it will make a lot of sense to display a progress meter, but
we are not there yet.
