At first, there was no such amount of clusters in dist config, they added when someone need to write some new cluster for tests. So let's move them to the clusters.xml that is deployed only for tests, and leave only default cluster. And cleanup also some configs that had been copied from dist config in the repo (about test_config_* integration tests, this should be OK, since there are more_clusters.xml as well, that covers additional cases).
