requested to merge hetsketch/gitlab-ce:display-deploy-key-title-in-error into master
Do not update/delete: Banner broadcast message test data
Do not update/delete: Notification broadcast message test data
Added key title for message on flash, while adding already existing deploy key.
The problem is when user has a lot of keys he don't know which key is matching and can't change the machine key.
master (if it does - rebase it please)
