Yes, I agree that it should be in the main distribution. Thomas,
Matthias, please co-ordinate between yourselves who'll add it in.
I agree also that the name with a "2" is confusing. We can either go
with
- check_cluster, with a clear statement in NEWS that this works
differently from the previous check_cluster in contrib
- a new name (check_cluster_states ? check_states?)
I would like some good tests for this plugin too, which should be
fairly easy to do as there is no external "thing" that needs to
return data.
