new feature: Allow s3 service to configure assume role's tags

[Xuanwo]

Feature Description

As requested by apache/iceberg-rust#527, it's better for opendal to support setting assume role's tags.

Problem and Solution

reqsign doesn't support tags for assume-role now. We will need to add it in reqsign first.

@rahull-p has completed most of the work in Xuanwo/reqsign#467, and we can proceed once reqsign releases a new version.
