1306887842,PR_kwDOAMm_X847g7WQ,6795,display the indexes in the string reprs,14808389,closed,0,,,7,2022-07-16T19:42:19Z,2022-10-15T18:28:36Z,2022-10-12T16:52:53Z,MEMBER,,0,pydata/xarray/pulls/6795,"With the flexible indexes refactor indexes have become much more important, which means we should include them in the reprs of `DataArray` and `Dataset` objects.

This is a initial attempt, covering only the string reprs, with a few unanswered questions:
- how do we format indexes? Do we delegate to their `__repr__` or some other method?
- should we skip `PandasIndex` and `PandasMultiIndex`?
- how do we present indexes that wrap multiple columns? At the moment, they are duplicated (see also the discussion in #6392)
- what do we do with the index marker in the coords repr?

(also, how do we best test this?)
