Don't know yet how to effectively test this, I guess there is some tricky solution with some mocking.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7523/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull

- [x] Closes #6632

So far we have not found a good way of typing dynamically added custom backends (installed via pip).
So the only fallback option is to allow str.

I have decided to leave the Literal as type, since it gives the user a nice list of supported backends in the editor.

Feel free to wait with merging after the 2022.05.0.dev0 release :)

- This PR adds typing to all Dataset methods (only the ones in Dataset directly and DataWithCoords).
- On the way it fixes several typing issues and adds small code changes for more consistent typing (hopefully does not break anything).
- All test_dataset tests are now typed.
- As usual there are still some mypy bugs open that prevent all typing changes to be final (especially https://github.com/python/mypy/issues/12846). I choose to remove the TypeVars in these occasions to prevent false positives on the user side.
- Sorry for updating so many files at once, mostly these are the changes of adding `from __future__ import annotations` and automatic fixes from pyupdate.

If anyone has some typing expertise:
I think that the way align is typed is wrong. The current implementation only works for aligning a sequence of objects of the same type, but not mixed DataArrays and Datasets. In some placed I had to add some ""#type: ignore""s...
I should probably open an issue for that.
