Reduce IRC notifications for gitlab.undeployed-builds --notify
Currently when one or more undeployed builds are found, the tpo/web/housekeeping
pipelines send notifications on IRC every two hours, which is a bit much.
Consider skipping those notifications for 24 hours when the task is called with --comment
: the hope is that since changes are usually merged in via MR, the comment will be enough to have the right person push the changes before an IRC notification is sent out.
