Update Grafana dashboards

Grafana.com is rejecting HTTP requests with basic authentication.
Earlier, it used to ignore the basic auth, and simply serve the request.
This new behaviour in Grafana API breaks the sidecar import feature of
Grafana's Helm Chart. The sidecar from Grafana uses basic authentication
in their HTTP request. It then gets a not-authorized response from
Grafana API, and dashboard importing fails.

GitHub raw URLs ignore the basic auth and simply serve the file as a
static element.
