Frontend: Support multiple metric alerts
Problem to solve
We need to add the UI for allowing users to configure multiple alerts. The backend support is being addressed in https://gitlab.com/gitlab-org/gitlab-ee/issues/12258.
We should add this into our existing alert interface, allowing users to easily add more alerts.
|One Alert||Multiple Alerts|
Permissions and Security
What does success look like, and how can we measure that?
Both the cluster health and metrics dashboards should be able to add multiple alerts
