As described in #9250, upgrading boto3 from 1.14.7 to 1.34.14 broke the current way we use AWS buckets across different regions.

Due to urgency, in #9257 we downgraded to 1.24.96 which is the latest version that supports both our current use of OCS-CI and other recent package updates that were required due to security needs.

However, since we can expect a need to upgrade boto3 again in the future, we need to adjust OCS-CI so we can use multi-region AWS buckets with the latest version of boto3.
