The change is unnecessary. It will create difficulties for future backports.

Tips from steveloughran

-1 to all needless import changes, even if cleanup. import changes are the nightmare of cherrypicks, which is why we so rarely clean them up, even ongoing patches. given a choice between "messy imports in existing code" and "backport hell", i will take the mess.

Middleware should be kept simple enough. Additional introductions may increase instability.

@jianghuazhu , I agree with @slfan1989 that this kind of changes may not be helpful.

Let's spend more time on the code but not on the imports. You have filed RATIS-2171. How is it?

There are also some test failures: RATIS-2261, RATIS-2262, RATIS-2175, etc. See if you would like to work on them.

Thanks @szetszwo for the comment and review.
I will try to fix these.
