Remove grafana areas from availability tests
Remove grafana areas from availability tests

Putting to the metadata resource significantly changes the positioning
of things in the pipeline

IMO the annotations for the tests (with build metadata) are not helpful,
although having lines for when they start and end would be. Build
metadata is not necessary because we can only run 1 set of availability
tests at once
