Title: MAINT: cluster: some clean up

* some useless docs, comments and code in cluster.vq are removed.
* the docstring of the `missing` parameter of `kmeans2` is added
* the docstring of the return value of `cluster.hierarchy.dendrogram` is updated. The description of `color_list` is added and `icoord`/`dcoord` are described more specifically.
