I don't think we need this warning any more; at least, you probably already know you're doing something wrong before you get to the question of importing dangling indices.

Looks like the tests already mock out the ClusterService, so I think we could pass in the metadata via that mock, have them call getDanglingIndices() and thereby inline this. Or have DanglingIndicesState track a Supplier<ClusterState> rather than the full ClusterService and pass that in for the tests. Not sure which I prefer really, up to you.

Don't think we need to mock this any more.
