This would probably make sense to send notification to the address from
which the Patchwork gets emails for parsing. In case of successfully
passed test, the bot can send an email with "Tested-by" tag, which will
appear automatically in the commit message in the patchwork (similar to
"Reviewed-by").

If you do not want to have "Tested-by ci-bot", just email with free text
would be fine, because it will appear on the Patchwork's web interface
anyways. In such a case, we could even send CI messages *only* to the
patchwork, without flooding the mailing list. And whoever interested in
reviewing the patch, will just look up the email from the bot on the web
page related to this patch.

In my personal opinion, just sending CI email as "reply-all" is fine. I
do not mind having an extra email per patch in my mailbox.
