Custom Grafana Annotations

[fnikolai]

When using services within a cluster the annotation use the auto-generated name (e.g, Benchmarks-1).

This is hardly helpful when using the cluster to run a test-suit.
Instead, we should be able to use custom annotations that include the test-name.

To do so, we must:

1. add grafanaDescription to the template's decorators
2. populate the grafanaDescription via values from inputs.
3. Use the grafanaDescription when generating the grafana annotations.
