Port SLA dashboard from Grafana to GitLab
This is a port of the SLA dashboard from: https://dashboards.gitlab.net/d/general-slas/general-slas?orgId=1&from=now-7d&to=now
so it can be used in our GitLab monitoring solution
Here's the dashboard running in the Dogfooding project on ops.gitlab.net
The single stat percentile values will be fixed when this is merged: gitlab-org/gitlab!28365 (merged)
