Tests: Query grafana datasource via UID (#1553)

* Tests: Query grafana datasource via UID

Set UID of datasources manually and use that UID to query using tests.
The older API is deprecated and soon to be removed.

* Also set Grafana datasource UID for kind tests

The kind tests uses a different than normal Grafana deployment, and as
such this config needed to be changed to include a UID as well.
