[ Metrics ] Grafana instances upgrade

Dear customers,

OVH Metrics Data Platform⚡ manage for you a free Grafana instance.

By the end of the week we intend to upgrade these Grafana instances in order to:

- Migrate the URL from https://grafana.tsaas.ovh.com to https://grafana.metrics.ovh.net.
- Update Grafana version 📈 (v4.3.0-pre1 => v4.6.3) and the Warp 10 plugin.

Following your feedback 💙, the sign-up process will be simplified, an organisation will be created for the user during the sign-up, so they will be able to work on dashboards faster 📊. The Warp 10 plugin has also been enhanced with a visual request editor and more intuitive script editor with auto-completion and syntax highlighting 📝.

To roll this upgrade, we have scheduled a service downtime 🚧 on 2018/02/23 10h00 UTC. The estimated duration of downtime is under one hour. During the downtime, other OVH Metrics Data Platform services won't be impacted.

Best regards,

OVH Metrics Data Platform team
