Suggested change

	from google.protobuf import field_mask_pb2 as field_mask # type: ignore
	from google.protobuf.field_mask_pb2 import FieldMask

Should we keep it unified with import in other places?

It just copied these lines from the Google library, but it will delete the alias, because it is not needed.

The PR most likely needs to run full matrix of tests because it modifies parts of the core of Airflow. However, committers might decide to merge it quickly and take the risk. If they don't merge it quickly - please rebase it to the latest master at your convenience, or amend the last commit of the PR, and push it with --force-with-lease.

Can you please rebase to latest version @mik-laj ? We will likely need to check if it works as intended with upgrading to latest deps.

The Pylint check in master is broken. Based on the files pointed by Pylint, seems it's related to this PR. I'm taking a look into it, also FYI @mik-laj @potiuk

[potiuk]

Strange. They seemed to pass in the PR.

[mik-laj]

I did a rebase this morning. i also have all the fancy labels for this PR, but it seems me the problem may be with the constraints file that contains the old version.
