Xarray: 0.12.0 release

[shoyer]

We have quite a few nice new features merged into master.

Is anything holding up making a 0.12 release shortly?

2759 looks ready and complements all the cftime stuff.

2769 seems like a nice bugfix to merge.

Otherwise lgtm.

I think #2721 looks ready too, and @jwenfai and @tlogan2000 would probably appreciate it if we merged it in time for the 0.12 release (sorry for letting that sit for a couple weeks).

I'd love to get #2777 merged - it's a small patch, but really useful in a remote sensing niche.

My students are going to be graded on how well their figures are labelled, and I really don't want to have to teach them matplotlib 😅

Potentially completing #2616 would start the deprecation cycle for auto_combine etc? I would need at least a few days to do that though...

[shoyer]

I'm going to cherry-pick https://github.com/pydata/xarray/commit/63da214d697345ebdd0ecc0967c72eafc70bcb0d and then try to get a release out.

We can start the deprecation cycle for auto-combine later.

[shoyer]

I guess we should probably fix and/or remove the failing test in https://github.com/pydata/xarray/issues/2803, too.

(I have let some of my PRs stay almost-finished. I will endeavor to follow my own advice and complete soon. Thanks for everyone's patience)

[shoyer]

Any objections to pushing back finalizing deprecations currently marked for 0.12? See https://github.com/pydata/xarray/pull/2809

I'm a little concerned that most of these changes (introduced in 0.11) haven't been around long enough to safely finalize the deprecations.

[shoyer]

I finally tagged the 0.12 release... probably should have done this a while ago!

Thanks @shoyer. I merged the conda-forge build about an hour ago.
