Currently, we utilize holds on our workflows to require a pair of eyes to check on deployments heading to production. While a great feature, it is often unclear when jobs are stuck in a "hold" unless you're glued to the CircleCI console and are acutely aware that a build is being executed on a branch that even needs an approval. It would be very handy to receive notifications for workflows in a "hold" status, as well as to even approve them through Slack! CCI-I-1028
