Should rename_dims also rename indexes (dimension coordinates)?

Yes, renaming dimensions and/or coordinates should be properly handled by indexes. Xarray's Index abstract class provides a rename method that may (should) be implemented in subclasses.

For example, PandasIndex and PandasMultiIndex both have a dim attribute that must match the dimension name (this attribute is required as in a near future it will be possible to set indexes for non-dimension coordinates).

PandasIndex.rename (PandasMultiIndex.rename) also renames the underlying pandas index (levels) according to the new coordinate name(s).
