The cluster info is important context for the cluster controller to create the cluster, and all the fields must be properly set. A test cluster name was being set temporarily, resulting in mons incorrectly getting the wrong cluster CR name. There is no known issue from the temporary value, it was just exposed by https://github.com/rook/rook/pull/8678 setting the value to a label. Now the functions are more clearly named so only unit and integration tests should be using the test value for the cluster name where it is not important.
