fix(aws): add soft error

[blanchardma]

Description

Fixes (again) #4067 because it was partly revert by #3973.

Add the ability to have a soft error when it fails to list resource records sets for zone. For example, if the cause of the error is the throttling of the AWS Route53 API Throttling: Rate exceeded' status code: 400 , it is certainly not helpful if it is not a soft error and flags to improve the situation such as --min-event-sync-interval can not work.

Checklist

• Unit tests updated
• End user documentation updated
  -> Both are not needed

Hi @blanchardma. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

@blanchardma thanks for this. Would you please update the tests accordingly ?

@mloiseleur can you be a bit more specific? Because the other PR #3973 in this direction don't have any and also the one that introduced the softerror #4166.
