ref #9307

Unfortunately CloudWatch dimensions are case-sensitive and it uses both `DBClusterIdentifier` and `DbClusterIdentifier` (notice the lower case `b`) depending on the metric. All metrics which also have the `Role` dimension appear to use `DBClusterIdentifier`, whereas metric with the `EngineName` dimension use `DbClusterIdentifier`.

A 'Github Application' is now something else, and will not work with Grafana.

ref #9279

`bus.AddHandler("sql", SetUsingOrg)` is already called on line 24.

Very minor change.
