Pin aiobotocore to lower than 2.0
- [x] xref #44311

LGTM pending green

do we need a comment about conditions under which the pin can be reverted? Would have tracked this through the issue, but could add a comment to  nice merge on green Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

```
$ git checkout 1.3.x
$ git pull
```

2. Cherry pick the first parent branch of the this PR on top of the older branch:
```
$ git cherry-pick -m1 28c7f7628dd6b862e1eed29ff71e2e8363ca1eee
```

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

```
$ git commit -am 'Backport PR #44315: Pin aiobotocore to lower than 2.0'
```

4. Push to a named branch :

```
git push YOURFORK 1.3.x:auto-backport-of-pr-44315-on-1.3.x
```

5. Create a PR against branch 1.3.x, I would have named this PR:

> "Backport PR #44315 on branch 1.3.x (Pin aiobotocore to lower than 2.0)"

And apply the correct labels and milestones.

Congratulation you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove `Still Needs Manual Backport` label once the PR gets merged.
