This PR adapts the node tools to work with the new Lucene-based cluster state storage mechanism. It also switches all node types to make use of this new storage mechanism (which simplifies the tooling), and reenables BWC on this development branch. It fixes dangling indices in a quick way that allows passing all the existing tests. There are more TODOs to be done there, however. Data-only nodes now also write the cluster state in the same way as master-eligible nodes. In a future PR, cluster state storage on data-only nodes will be made async.
