In the previous change we added this security feature for changes that are submitted with sticky approval. This change extends the feature to not only add a change message as done in the previous change, but also adds this information to the email about the merged change. Neither the email nor the change message are supported for direct pushes. Change-Id: I723721251194d6a90ffdbc4b3f80cf30782aaf84
