Add users email to auto-generated gerrit patches

Add users email to auto-generated gerrit patches

- the --reviewers option is not there in the current version of
  git-review (1.24) but is there with v1.25 which will be
  installed with the pip install command in this patch

- this would add me (jluhrsen@redhat.com) to all auto-gen
  gerrit patches, and I don't mind, but I need to get these
  reminders for the csit auto-gen gerrits at the least. Maybe
  there is a better way to do this?
