The moving operation changes a node's token to a new token. It is supported only when a node has one token. The legacy moving operation is useful in the early days before the vnode is introduced where a node has only one token. I don't think it is useful anymore. In the future, we might support adjusting the number of vnodes to reblance the token range each node owns. Removing it simplifies the cluster operation logic and code. Fixes #3475 Message-Id: <144d3bea4140eda550770b866ec30e961933401d.1533111227.git.asias@scylladb.com>
