The seaborn.apionly entry-point has been removed.

[mathause]

Seaborn recently dropped the apionly entry point (in version 0.10.0).

There is a dedicated import_seaborn function

xarray/xarray/plot/utils.py

Line 24 in 47a6fc0

def import_seaborn():

but it is not used in one place

xarray/xarray/plot/utils.py

Line 146 in 47a6fc0

from seaborn.apionly import color_palette

which now causes test failures

https://dev.azure.com/xarray/xarray/_build/results?buildId=2111&view=ms.vss-test-web.build-test-results-tab&runId=29632&paneView=debug&resultId=108176

Todo: double check if the supported versions of seaborn still require this workaround.

[mathause]

The apionly entrypoint has been deprecated in seaborn 0.8.0. The minimum seaborn requirement is currently 0.9.0:

xarray/ci/requirements/py36-min-all-deps.yml

Line 45 in 4c96d53

- seaborn=0.9

So I think the def import_seaborn function can be dropped.
