Release arrow ~10.0.0~ 9.1.0

[alamb]

EDIT: suggestion is to release this as arrow 9.1.0 as there are no breaking changes.

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Arrow 10.0.0 is scheduled for release (RC on Feb 18, 2022 release on Feb 21, 2022 if we follow the same schedule as other releases)

I will not be able to contribute to the project for these dates as I will be away, though I will be available again starting Feb 28 2022

Describe the solution you'd like
This might be a great time for some others to try out creating a release if they are available and are interested in doing so

The instructions are here:
https://github.com/apache/arrow-rs/blob/master/dev/release/README.md

I believe you need to be a committer to run the ./dev/release/create-tarball.sh 4.1.0 2 script, but making the changelog and updating the version would be straight forward.

@andygrove @kou and @kszucs have access to publish on crates.io.

Describe alternatives you've considered
An alternative is to postpone the release until sometime after Feb 28

Additional context
Arrow 9.0.0 was delayed by about a week due to some issues encountered while testing. See https://lists.apache.org/thread/2yyq5x7cx4f16q68x8vlftf3ksbrckxb for more details

I'd be happy to help out with preparing the release, but would of course need the assistance of a committer to cut the actual release. It may be easier for a single committer to handle the whole thing, but thought I'd offer 😄

It's a good idea!

I can help the committer as a PMC member.

The part of the process that is not entirely mechanical is the creation of the release notes, but since ideally that is done by editing labels and titles of resolved issues, I am not sure what permissions are required to do that

[alamb]

As I think @tustvold isn't on the committers list he will not be able to make changes to the issue titles or labels nor merge PRs as appropriate.

Would one of the existing Rust committers be willing to help? @Dandandan @nevi-me @paddyhoran @andygrove @rdettai @sunchao @jimexist ?

[nevi-me]

I can cut an RC over the weekend, on Saturday

[alamb]

Thanks @nevi-me -- I'll try and make a PR with some proposed release notes and a version bump as well to help out

#1325

[alamb]

After reviewing the changelog, it seems like this could actually be a 9.1.0 release (see comment from @tafia #1120 (comment) ,

Thoughts @tustvold ?

[tustvold]

@alamb We are of the same mind 😆 - #1325 (comment)

[alamb]

Cool will update the versions in #1325

[tafia]

Thanks !!

[alamb]

Thank you so much @nevi-me and everyone else who helped with this release!

[rdettai]

sorry for not reacting to this, this last months have been very busy for me! I'll try to help out next time 😉
